Heat Treat Radio #95: Heat Treat Legend John Becker

We have the honor to speak with another Heat Treat Legend in our industry, John L. Becker, president and founder of Heat Treat Equipment. Doug Glenn, publisher of Heat Treat Today and host of this podcast, has been chatting with the legends walking among us who’ve been involved with the North American heat treat to get a sense of where they’ve been, what they’re doing, and what advice they would share with the current generation. “Tenacious” is the word that comes to mind from this conversation.

Below, you can watch the video, listen to the podcast by clicking on the audio play button, or read an edited transcript.


 



The following transcript has been edited for your reading enjoyment.

A Summer at Ford Motor Company (01:20)

Doug Glenn: John, you were the founder and owner of the J.L. Becker Company which was recently purchased by Gasbarre Furnace Group. You’re no longer associated with that company, since you sold it. You are associated with Heat Treat Equipment, Inc., which you also started.

Contact us with your Reader Feedback!

How did you get started in the heat treat industry?

John Becker: It goes back to the summer of 1964 when I had been going to a junior college, and I started dating my wife. Her father was in the steel division at Ford Motor Company, and I needed a summer job in 1964. Through his contacts, I was able to get a job there. My position was very "prestigious." I had my own tool; it was called a broom! Through sweeping up, I was a first-class janitor. Then, I was able to move up to a helper’s position.

In working there for the summer, I saw a lot about the making of steel and the production processes. I used to hang around the lab, because in the summer, the lab was air conditioned; and I could pretend that I was interested in that area. By the end of the summer, they asked if I would consider going on co-op for metallurgy. I thought, “Well, that sounds easy. I can do that,” not realizing what I was in for.

"I received a BES in 1968"

I started in metallurgy, and worked for Ford and went to Western Michigan University where I received a BES (Bachelor of Engineering Science) in 1968. During that time of co-op, I worked and took classes. I used to take classes at Wayne State, Lawrence Tech, and other places where I could get some hours or get a class.

After I graduated, they put me in an area called the AADGO (Automotive Assembly Division General Office) where I was a fastener engineer. We were dealing with nuts, bolts, screws, and washers. I started visiting heat treat shops. At the same time, they put me on the MBA management program through the University of Michigan.

There were a lot of people in Rockford, IL, that made fasteners. One of the areas we were concerned with was heat treating. That thing called the Delta or appendix C, the Q101 (Quality 101 points) for Ford.  I would go around inspecting plants, and I got to know several people in heat treating. I was a bit fascinated by it.

In 1970, Ford laid me off. I was still finishing up school, and I had a child. I actually started teaching school part time and did that for a while. I was a “the permanent substitute,” so I would work a lot of different days. That was quite enjoyable!

I started working for a company that sold high temperature materials: conveyer belts, etc. and was pretty successful. I looked at what I was getting paid. At this company, some reps were getting 10%. I was getting a salary and expenses, and I understood that it was a pretty good deal. But I still looked at reps and figured I made 10% of that value.

Starting a Business in a Basement (06:18)

I decided to really go on my own, and I started the J.L. Becker Company out of my house as a rep. I had four principals, and a few others in the industry. I didn’t represent these, but I could sell their products. Two examples were the wire mesh conveyer belt of Canada and I Squared R, which provides silicon carbide heating elements. We had a line of hearth plates, thermocouples. I became the Lockheed engineering rep. Because of that, I called on a lot of OEMs like Surface Combustion and Atmosphere Furnace and others.

"My dad gave me an old phone."

We built it up. Everybody in Michigan had a basement. My dad had given me a used desk and, in those days, you had a phone that was wired to the wall. My dad had given me an old phone, so I started a company. In the basement of the house, I had a little cubby, about 4 ft by 7 ft, and that was my world headquarters.

After 6 months, I started to interview for a new job with salary and benefits, and all the things I didn’t have, because it wasn’t as great as I thought.

I had been calling on Monroe Auto Equipment in Monroe, Michigan. Monroe Auto Equipment has four plants that do powdered metallurgy; they make components for shock absorbers. I had become friends with a guy there, Fleming Pruitt. I still remember his name to this day.

He called me and asked for a particular product. I got a price for it, called him back, and he said, “I made a mistake. I didn’t want 20 pieces, I wanted 200.” I was going to make 10 bucks a piece or some number like that. All of a sudden, I was, like, “Whoa!” That started it.

Then I got another order, another order, and another order. Over time, I started thinking: “Why don’t I have some of my own products where I can control the price?” I could buy it for X and add my overhead to it.

Growing the Business (09:13)

In 1974, I moved to an office in Livonia, Michigan. It was in a multitenant-type building, and the fellow had rented two spots, and there was one empty office. I started there. I ended up hiring a gal by the name of Carol Campbell, right about then, for $90 a week and no benefits. She did an outstanding job for me.  Around 1976, I hired Dave Peterson. Dave still, as you know, works with me today. I couldn’t chase him away. I tried and failed.

"I added another piece of the puzzle."

From there, I added another piece of the puzzle. Each year we expanded. I got busy enough where I visited someone who I was selling different components to, and they had a piece of equipment they wanted to get rid of. I had visited someone else the day before who was looking for the same thing. I didn’t have to be that bright to understand that this guy wanted a dollar, and this guy was willing to pay two dollars. That worked out pretty well, and I did that a few times. But then the next time I did it, the person said, “You need to take it out.” So, I was able to; there was a group of guys and my office, at that time, was right behind Holcroft in Livonia. I got to know a lot of guys that worked there, and they would come and work for me on weekends. We would dismantle, move things, and ship them out.

Eventually, I got a little shop. I hired a fellow, whose name is Charlie Hatala, who now has Great Lakes Industrial Furnace. Charlie ran the shop, and then we started refurbishing equipment.

Then, in 1978 or 1979, BorgWarner Corporation in Michigan asked me if I could build a tempering furnace. I was doing maintenance for them installing components. I did a lot of brazing and sintering furnaces and some batch furnaces. They needed to do temper. I said yes, having never done it before.

Eventually, we figured it out.

I hired an engineer who worked for us part time for a while, and the shop became a busier situation. We started to build some equipment.

I hired an engineer, a fellow by the name of Don LaFore, who has now passed away. Don came in and helped shepherd us along to do design work. We started to build some belt-type furnaces for sintering and brazing. There were other people in the industry who had small operations to do refractory work or do electrical. We leaned on those individuals and started to build.

By 1980, I had two guys in engineering, Dave in sales, Carol in the office, and my wife, Eileen, was our CFO, as she still is today. It just went from there!

By 1983, we moved to another larger building.

In 1989 we moved again, and then in 2000, we moved to an even larger facility.

So, we had gone from about $700k–$800k to about $25 million in my last couple of years. In fact, we have equipment we built in the Ukraine for which my son, Matt, did the startup. We just looked at it in satellite, and it’s still standing and hasn’t blown up yet. That particular system, we duplicated twice for Russia.

Becker Goes International (14:16)

We built equipment in Israel, Dubai, Saudi Arabia, Thailand, and China. Korea was the first place, out of the country, where I sold a piece of equipment. That was right at the beginning, probably in the later part of the 1970’s, maybe very early 1980’s.

At Ford Motor Company, there was a research scientist; he was a Korean doctor. He  had gone back to Korea to head a thing called KIMM (Korea Institute of Machinery and Materials) and he called me and ordered a furnace. We built the furnace, a research-type sintering furnace and endo generator, and I actually went to Korea and did the startup. That was one of the first international ones. We’ve shipped equipment to Canada, to Mexico, and to quite a few different places.

At 68 years old, in 2011, I sold the company to Gasbarre.

 Becker’s Network in the Heat Treating Industry (16:02)

Doug Glenn: Give us a recap of some of the people with whom you’ve interacted.

John Becker: There was a startup company in around 1970/71 called Custom Electric Furnace, where Tim Mousseau worked as an engineer. Charlie Hatala was basically the president and shop manager. They had all come from a company called Alexander Engineering which goes way, way back.

I started repping them, and I sold a few furnaces for them.

Another guy that was repping around there was Jeff Smith; he worked for the which represented a company out of New York that made heat exchangers. Jeff came up with the idea of making his own heat exchangers, and that’s when they started SBS Corp.

During that same time period, I became friends with John Young. John’s father had Perfection Heat Treating Company, and his father, unexpectedly, died just before Christmas around 1976, I believe. John and I became friends. His wife’s name was Eileen, and my wife’s name was Eileen. We both had degrees in metallurgy; our backgrounds were very parallel to one another.

John and I ended up buying the heat treating company called Steel Improvement Company, and John ran that company successfully for about 10 years. Also, John and I got in on a few other companies too.

1984 and 1985 hurt the heat treat industry in Detroit, so we ended up liquidating both those companies.

Just like Jeff Smith, people from, refractory people, we interfaced with so many people here. In the metropolitan Detroit area, you have everything you can think of: Electrical supplies, wire, refractory, engineering help, machining, fabricating, steel suppliers. Everything is right at our fingertips. You have a real cornucopia of support-type people from lawyers to accountants to medical to whatever. It was a good place to nurture a company.

Like I said, we built the company up, and I was really motivated to sell.

In 2009, my oldest boy died. That hurt me personally, obviously. Then, in 2010, my younger son, Matt, who’s kind of a Mensa kid, announced he was going to leave to open a brewery. He has been extremely successful.

Then, Gasbarre approached me. My thoughts of passing the business on to my sons were trash, so I sold the company. After I sold it I consulted with them for a couple years; it was all part of the contract. I realized I really didn’t want to get out of it; I had pulled the trigger a little too quickly.

I’m 79, and I still work almost every day. I love the business, and I’ve come to know so many people in the business that I interface with. I’ve had some very, very strong supporters over the years for the equipment that we’ve built.

One guy that was probably the nicest guy — you couldn’t have asked for a better friend — was Jim Hendershot who had Carolina Commercial Heat Treat. Jim sold it to Gibraltar and on and on. Now, most of their plants are part of Bodycote.

John’s Supporters (22:32)

Doug Glenn: Are there two or three people who had a significant impact, people that encouraged you to carry on?

John Becker: You know, I really can’t point to anybody individually. Obviously, my wife was a supporter. She was burdened with the accounting side of the business.

"It was more people believing in me..."
Source: Unsplash.com/Brett Jordan

I had a lot of different people. There was a buyer at Ford who was very supportive. Another guy at AC Spark Plug up in Flint; I did a lot of work for them and built several pieces of equipment. So, it was more people believing in me and believing that I could do the job and giving me the opportunity to do it.

My best friend just passed away a week ago (he was a Ford dealer). He would listen to me all the time and give me advice. He had built up a company where he was the number one Ford dealer for 1921 and 1922 in volume, worldwide, in the small little town of Livonia. It was very prestigious. He was a very well-liked individual. He gave me a lot of advice about not trying to micromanage, about giving up control and giving control to other people, hiring people and trusting them to let them do their job, and how to treat individuals. I think I learned a lot from that.

John’s Significant Accomplishments (25:20)

Doug Glenn: What are one or two your significant accomplishments?

John Becker: Dave Peterson worked with a company (and I won’t mention their name), and I joined him. This company had bought a used piece of equipment and did some converting on it to do a process. They had built one, and then we built their next one and “upgraded” it to the next phase.

We worked on the design and built and built and built it to where they had about 50 of these units. I think, between myself and Gasbarre, there may be 55 of them built. If you look at it, it’s roughly a million dollars apiece; they were very successful. They were using my son, Matt, who developed the software and automated all the controls to mass flow sensors, etc. This was early on before a lot of things that we have today. If you look back, this was all new technology at the time.

That was a “feather in our cap,” and that was a whole team. The engineering department did the engineering, the shop and the people in fabricating all had ideas and those were incorporated into it, and Matt redeveloped the software and the controls and developed all the programming. Before they had a lot of mechanical and timing issues where a bell would ring and an operator would have to do something, this was all automated. It took the operator out of what was a 30, 40, 50-hour process.

It’s very successful. That shows how the whole group pulled together and did it.

"I'm tenacious like a bulldog..."
Source: Unsplash.com/MattODell

My success has been talking. Sales. I’ve been able to connect with people. I’m tenacious like a bulldog on an ankle; it’s hard to get me off. My middle initial is “L” and I tell everybody it’s for “Lucky.” I’ve been very fortunate to have a very loyal group of individuals. Like, we’re here now at Heat Treat Equipment. Bill Richardson started me in 1980 and was chief engineer and is with me now. Dave Peterson was my sales manager since 1976/77 and is with me now. The people in our shop, I did not solicit them. They came to me. When I had J.L. Becker, they were the ones that made the clock work.

I would go out, do the sales, contribute to them, and try to close the deal. I had more people — we had four or five gals, plus the CPA, plus my wife in the office, for insurance, employee benefits, payroll, paying the bills, etc. That worked very well, but that wasn’t my department. I looked at it macro work, but the micro work was done by all of them. They were very organized. The same was true for the shop and in engineering.

I really have to say they’re the ones that made the business keep moving. I would come in and say, “I’ve sold another standard piece of equipment except everything is different.”

Lessons Learned (30:43)

Doug Glenn: Over your work career, were there any disciplines that you developed? Were there any disciplines you developed you felt were beneficial for you and for your company?

John Becker: I can’t think of anything specifically. They always say, “Never quit. Never take ‘no’ for an answer.” So, I never quit. I used to tease some of the other guys because they would call on a customer for years, literally 4–10 years, and nothing would happen. Then, there was that lucky change in personnel. All of sudden, everything started to happen. We became “their guys.”

I was tenacious, and I listened. I do a lot of talking, but people don’t realize I do listen. Understanding, in sales, what does your customer want, what’s the expectation? I’m not going to pick on any other company, but some, more or less, “fell from the catalog.”

I always thought we were willing to change to try to modify or make our equipment fit our customer’s needs, not our customer needs fitting our equipment. We always went in and would change things. As I said, “Another standard piece except everything is different!”

I know when I sold the company, Gasbarre enjoyed quite a bit of repeat business from our customer base. I think our customer base was loyal; the loyalty came back from being loyal to them. We, like everyone else, had problems. My point was: We need to fix the problem, not fix blame. We didn’t worry about the cost. When it was done and resolved, then we could go back and look at it to find out if the problem arose from something we did, was it improper usage, etc.?

We never walked away from a problem and trust me, I had them over the years.

Doug Glenn: Did you ever lose any big money on them?

John Becker: Yes. More than once, and we lived to tell about it! The problem was sometimes I was quick on the draw. A guy that draws fast can shoot his foot off. The gun goes off a little too quick. Every time I would try to jam a square peg into a round hole — like I said, I was tenacious. I would fight and fight and fight for an order and get it and get creamed.

Work-Life Balance (34:55)

Doug Glenn: How did you handle work-life balance?

John Becker: It was never a struggle. I worked 6 days a week; when the kids were growing up, I coached baseball. I had a soccer team I coached in Northville for both my boys. We loved Florida because my grandparents were down there. My mother’s parents were down there, and my parents moved there. I had a brother and sister that lived there, etc.

We started going down to Florida very early in our lives in the 1970’s. We took vacations with the boys. There are plays and things they did at school; we did all that. We had a pretty good life.

Over the years, I’ve developed a lack of memory. When I walk out the door of work, my memory just falls off somewhere. I’m driving home and when I get home, I can’ remember things. Even though Eileen was involved in the business, I didn’t go home and talk about the business. I left it at work.

[blockquote author="" style="1"]One thing I’ve learned is that the work you didn’t do today will be there tomorrow. The work will be there.[/blockquote]One thing I’ve learned is that the work you didn’t do today will be there tomorrow. The work will be there. Early on, I did a few things. I missed a funeral for a friend that I still look back at, 30 years later, and say, “I could’ve cancelled or rescheduled those appointments, and I could’ve gone there.” I still think I should have gone to the funeral, and I didn’t and I’m sorry, today. The appointments that I went to never turned out to be anything.

I’ve always carried that around, that I should have been there for that person even though they had passed. You make decisions, and I think you’ve got to remember that a lot of these things will be there tomorrow that you don’t get to today.

Advice to Young Leaders in the Industry (37:48)

Doug Glenn: Were there one or two lessons you learned along the way, words of wisdom you would give?

John Becker: Send your resumes out somewhere else? Find a different career! I don’t mean that; the industry has been good to me.

I think that one of the things for younger people, especially in sales, is this: I would go work on a sale and I would think, “Boy, I’ve got this thing,” and find out I lost to a competitor, not realizing the purchasing guy’s brother-in-law was my competitor. So, understanding the politics of situations, the relationships. I’ve had people that I’ve been very, very close to and they would go out for bids, but I knew I was getting the work. Get to understand the relationship, who they’ve worked with in the past.

The other thing I think is important is technical society. I belong to ASM (ASM International, formerly known as the American Society for Metals). I used to belong to MPIF (Metal Powder Industries Foundation), the APMI (American Powder Metallurgy Institute).

I was one of the original associate members of  MTI (Metal Treating Institute), but actually I was an MTI member back in the 70’s because we (John Young and I) owned the heat treat shop. John was the member, and I was the alternate. They were very, very down on a salesperson, like me, coming to those types of meetings. I did go to a couple. In fact, the very first or second meeting that Lance ever had, I met a guy who was from out in Oklahoma, by the name of John Hubbard. That was back in, probably, 1980, roughly, ’81 maybe; it was in that time.

Doug Glenn: So, for those who are listening that might not know, Lance Miller was the executive director of the Metal Treating Institute (not anymore, Tom Morrison is currently in that position). John Hubbard ended up being the CEO of Bodycote for years and years.

John Becker: I think in establishing relationships, try to be as honest as you can with your customers. There is a certain point that, I think, to maybe be a little guarded in your answers. Be as honest as you can without giving away your company secrets or whatever. Say you’ve had something in the background in your company that’s gone on and it’s affecting something. You don’t need to broadcast that, but you should maybe tell your customers you’ve had some issues that are going to delay or change things. That’s the best thing.

Just be yourself; don’t try to be somebody else. And you know what, if you don’t come home laughing and having a good time and enjoying yourself, you’re in the wrong business.

Tip-Ups: A Viable Solution To Customize Your Heat Treat Department

OCHeat Treat Today asked tip-up manufacturers to help heat treaters understand the variability of tip-up options in the market today. In this article, Gasbarre Thermal Processing Systems and Premier Furnace Specialists share unique approaches on how their own gargantuan furnaces serve heat treaters. As you read, note that customization is the critical component to operating a tip-up in your heat treat department.

This original content article is drawn from Heat Treat Today's February Air & Atmosphere Furnace Systems print edition. Have something to share about tip-up furnaces? Our editors would be interested in sharing it online at www.heattreattoday.com. Email Bethany Leone at bethany@heattreattoday.com with your own ideas!


Gasbarre Thermal Processing Systems

What is your system and how does it differ from historic tip-up systems?

Gasbarre has a unique offering of tip-up style furnaces. We offer systems for conventional applications such as austenitizing, solution treating, stress relieving, and tempering. In addition, we also offer atmosphere processes such as annealing and ferritic nitrocarburizing (FNC). For us, tip-up systems are not one-size-fits-all type systems. Systems are designed around our customer’s specific processing requirements. This would include thermal process requirements, load geometry and weight, temperature ranges and uniformity requirements, as well as time to quench specifications.

What are its operational advantages?

Contact us with your Reader Feedback!

When evaluating a tip-up furnace system, they are typically compared against box-style furnaces and car bottom furnaces. So, what differentiates a tip-up from these other style furnaces? First, you can achieve the main goal of large capacity batch processing, while gaining advantages over box furnaces with wider temperature ranges and tighter uniformity requirements. Box furnaces are more challenging to evenly distribute heat due to the large space requirement for the furnace door, where it is difficult to include heating elements or gas fired burners. Second, you can achieve faster time-to-quench speeds in a tip-up furnace over a car bottom furnace. Car bottom furnaces require the load to be pulled out of the furnace and then the load is typically manually moved from the furnace hearth to the quench. In a tip-up, this process can be automated and completed in 60 seconds or less. Finally, when special atmosphere processes are required, a tip-up furnace offers a superior atmosphere seal to the other furnaces mentioned. With tip-up furnaces, you can seal the furnace using its own weight. Other furnaces require additional mechanical assemblies to achieve a proper seal, which ultimately is more susceptible to leaks and requires more maintenance than a tip-up furnace seal.

Why should people be paying attention to what you have to offer?

Gasbarre’s broad product offering gives us the ability to evaluate your requirements objectively and offer the best solution for you and your company, whether that be box furnace, car bottom, or tip-up. Tip-up furnace systems are usually not one-off installations. These systems usually involve quenching equipment, material handling, load staging, and other integration. Gasbarre has the experience and personnel to manage such large projects and support the customer to effectively implement a system.

Premier Furnace Specialists

What is your system and how does it differ from historic tip-up systems?

The controls and automation capabilities of our furnaces set us above many older systems still in use today. On the control panel of an older system, you’re likely to see paper chart recorders, maybe a PanelView screen, and dozens of switches, pushbuttons, and pilot lights. Some of our customers prefer these control systems for their familiarity, and that’s fine because we are capable of building this style of enclosure, but most come to us for improvements or new systems entirely. Our standard panel comes with a 23.8” color touchscreen display that lets operators manage or record almost every aspect of the furnace’s operation. This package can be added to existing furnaces as well, as we have performed many control and combustion upgrades on older systems to keep them functional and reduce operating costs. We also offer tip-up furnaces that operate via jackscrews for customers who want to avoid the maintenance and flammability of hydraulics.

Modern burner technology also offers a massive improvement over older systems. With rising energy costs for all fuel types, any increase in efficiency will quickly become a source of savings which can be redirected into other areas of your company. Improvements to burner design offer increased preheat, recuperative, and regenerative possibilities, which offer fuel savings across multiple temperature ranges and reduce emissions to keep in line with changing regulations. A standard burner can heat up and cool down faster, take less time to tune, and reduce maintenance hours and headaches compared to older models of burners with knowledgeable air and gas train design coupled with modern burners.

What are its operational advantages?

Our systems allow greater flexibility for integration with existing and future equipment as well as simplified operation. One of the largest complaints we hear in every industry is about the struggle to retain maintenance and equipment operators’ knowledge once a senior member leaves a company. For this reason, it is important to have a simplified controls interface that allows new operators to get up to speed quickly. As a service company as well as an OEM, we have extensive experience working on and upgrading many brands of equipment. This enables us to easily integrate our solutions to match what customers are familiar with while also reducing maintenance requirements.

Why should people be paying attention to what you have to offer?

Despite OEMs trying to convince you, sometimes a standard “cookie cutter” model just isn’t the right fit for a job. It can take years to build up a budget for a new furnace system. Don’t invest those hard earned dollars into a piece of equipment that won’t do everything you need, exactly how you need it done. We are willing to take on the jobs that require creative solutions and extensive automation. Premier’s custom engineered systems live up to our namesake. Some of our recent projects have included a 130 ft long roller hearth furnace system with automated cooling/sequencing/handling of over 40 loads simultaneously; and a car bottom furnace with a 15’ x 15’ x 15’ work chamber capable of controlled heating and cooling of 160,000-pound loads.

Elevate Your Knowledge: 5 Need-to-Know Case Hardening Processes

OCYour parts need heat treated to herculean surface hardness but with a soft, ductile core. That is to say, you are looking at case hardening processes, most likely one of these: gas carburizing, low-pressure carburizing, carbonitriding, gas nitriding, and ferritic nitrocarburizing.

Mike Harrison at Gasbarre Thermal Processing Systems brings us a Technical Tuesday article about what case hardening is and how five of the most common processes vary by (1) comparing the specific guidelines for each temp and time, (2) identifying equipment used to perform each process, and (3) providing a chart (at the end!) to understand different process considerations.


Mike Harrison
Engineering Manager of Industrial Furnace Systems Division
Gasbarre Thermal Processing Systems

Case hardening falls into a class of heat treatment processes that typically involve the addition of carbon and/or nitrogen to the material through solid-gas reactions at the surface followed by diffusion. These processes are performed for any number of reasons that generally include increasing strength and wear resistance, but in all cases the end result is a harder, higher-strength surface with a softer, more ductile core.

Case hardening processes can be divided into two subsets: those that include quenching to harden, such as gas carburizing, low-pressure carburizing (LPC), and carbonitriding; and those that do not include quenching, such as gas nitriding and ferritic nitrocarburizing (FNC). This article will provide a brief look into each process, the types of equipment used, and considerations for implementation.

Diffusion + Quenching Processes

These processes involve heating the workload to austenitizing temperature, which is above the upper critical temperature for the material in question, then supplying and allowing the desired element(s) to diffuse into the part surface, followed by rapid cooling (quenching) to create a phase change to martensite that strengthens the material. Tempering is then performed to create a material that has the desired final strength and ductility properties. The result is a high concentration of added elements on the surface that continually decreases through diffusion until eventually matching the same concentration as the base material; this gradient similarly produces a hardness that is higher at the surface, gradually diminishing until reaching the core. Higher alloyed steels may also see a microstructural change in the core from quenching that produces a core with higher hardness than the previously untreated material, but lower than the surface hardness produced.

Atmosphere Gas Carburizing

Gas carburizing is a process where carbon is added to the material’s surface. The process is typically performed between 1550-1750°F, with carburizing times commonly between 2-8 hours; of course, these values can vary depending on the material, process, and equipment. The most common atmosphere used for atmosphere gas carburizing is endothermic gas with additions of either natural gas or propane to increase the carbon potential of the furnace atmosphere. Common case depths achieved are around 0.005-0.040”, with deeper cases possible through a combination of longer treatment times and/or higher temperatures.

Fig. 1 – Integral quench furnace: "The atmosphere gas carburizing process can be performed both in batch and continuous equipment."

The atmosphere gas carburizing process can be performed both in batch and continuous equipment. On the batch side, traditionally an integral quench (IQ) furnace is used (Fig. 1); it consists of a heating chamber where the workload is heated and exposed to the carburizing atmosphere, then the workload is transferred to an attached quench tank for cooling. The entire furnace system is sealed and under protective atmosphere to preserve the part surface and maintain safe control of any combustible gases. For batches of large product, a pit furnace can be used for carburizing with the workload being transferred via an overhead crane into and out of the furnace to a quench tank.

For continuous processing, a belt furnace can be used. The product is placed on a belt and then progresses through the furnace at the desired temperature and atmosphere composition; the carburizing time can be varied by adjusting the belt speed through the furnace. At the end of the furnace, the parts drop off the belt into the quench tank. Then, a conveyor pulls the parts out of the tank and drops them on another belt to be washed and tempered. For continuous processing of heavier loads pusher furnaces, rotary retort, rotary hearth, and roller hearth furnaces can be used.

Fig. 2 – Endothermic gas generator: "To achieve a carburizing atmosphere endothermic gas is typically used, which is produced by an endothermic gas generator that heats a combination of natural gas and air to create a mixture that is approximately 40% hydrogen, 40% nitrogen, and 20% carbon monoxide."

To achieve a carburizing atmosphere endothermic gas is typically used, which is produced by an endothermic gas generator (Fig. 2) that heats a combination of natural gas and air to create a mixture that is approximately 40% hydrogen, 40% nitrogen, and 20% carbon monoxide. This mixture is generally considered carbon-neutral, meaning it will neither add nor deplete carbon from the surface. To increase the carbon concentration the endothermic gas needs to be enriched with a gas (typically natural gas or propane) that will help produce additional carbon monoxide, which will “boost” the carbon potential and drive carbon diffusion into the material.

A less common carburizing atmosphere comes from a nitrogen-methanol system, where nitrogen gas and liquid methanol are combined and injected into the furnace. Upon exposure to the high furnace temperature the methanol will decompose to hydrogen and carbon monoxide. Natural gas or propane additions are still required in order to provide carbon for absorption into the surface of the steel.

Low-Pressure Carburizing

Low-pressure carburizing (LPC), or vacuum carburizing, is a variation of carburizing performed in a vacuum furnace. Instead of the atmospheres mentioned previously, a partial pressure of hydrocarbon gas (such as propane or acetylene) is used that directly dissociates at the part surface to provide carbon for diffusion. After LPC, the workload is transferred to a quench system that could use oil or high-pressure gas, typically nitrogen. LPC with gas quenching can be an attractive option for distortion prone complex geometries as the cooling rates are slower than oil quenching; however, given the slower cooling rate, it becomes very important to choose a higher alloyed steel that will achieve the desired hardness.

Fig. 3 – Vacuum furnace with oil quench

LPC typically provides faster carburizing times when compared to traditional gas carburizing. This can be attributed to a more efficient reaction of the hydrocarbon gas used and to the option of using higher carburizing temperatures, typically up to 1900°F. This is made possible by the type of internal furnace construction of vacuum furnace design, although care must be taken at higher temperatures to avoid undesirable grain growth in the material. LPC also has the benefit of eliminating the potential for intergranular oxidation, since it is running in a vacuum system.

LPC is typically performed in a single-chamber vacuum furnace, with oil quenching or high-pressure gas quenching done in a separate chamber (Fig. 3). Continuous vacuum furnaces can also be used in applications that require increased throughput (Fig. 4).

Fig. 4 – Continuous vacuum furnace

Carbonitriding

Despite its name, carbonitriding is more closely related to carburizing than it is to nitriding. Carbonitriding is a process where both carbon and nitrogen are added to the material surface. This process is typically performed in a range of 1450-1600°F and generally produces a shallower case depth than carburizing. Carbonitriding is used instead of carburizing for plain carbon steels that do not contain enough alloying content to respond well to quenching, as the added nitrogen can provide a higher hardenability in the case to allow for proper hardness development.

Atmosphere carbonitriding can be performed in the same equipment as is used for carburizing. The furnace atmosphere is still typically endothermic gas-based and includes the addition of ammonia to provide the nitrogen. Vacuum carbonitriding with both hydrocarbon and ammonia additions can also be performed in the same equipment as used for vacuum hardening and low pressure carburizing.

Diffusion Only Processes

These processes involve heating the workload to a temperature below the austenitizing temperature, allowing the desired element(s) to diffuse into the part surface, then slow cooling. The increase in hardness at the material surface comes only from the addition of the diffused element(s), and not from a phase change due to quenching. As these processes are performed below the lower critical temperature (i.e., below the austenitizing range), the desired core hardness and microstructure need to be developed through a separate heat treatment prior to case hardening. Generally, the process temperature selected should be at least 50°F below any prior treatment temperatures to avoid impact to the core properties.

Gas Nitriding

Gas nitriding is a process where nitrogen is added to the material surface. The process is typically performed between 925-1050°F; cycle times can be quite long as the diffusion of the nitrogen is slow at these temperatures, with nitriding times typically ranging from 16 - 96 hours or more depending on the material and case depth required. Nitriding can be performed in either a single or two-stage process and has the potential to produce two types of case, the first being a nitrogen-rich compound layer (or “white layer”) at the surface that is extremely hard and wear-resistant but also very brittle. This compound layer depth is dependent on processing time. In the more traditional two-stage process, the case depth produces a gradient of hardness from surface to core that commonly ranges from 0.010-0.025”, with minimal white layer, typically between 0-0.0005”. Nitriding is typically performed on higher alloyed steels or steels specifically designed for the nitriding process (e.g., Nitralloy®) as it relies on the formation of nitrides to create the increased hardness, which is achieved through the use of nitride-forming alloys such as aluminum, molybdenum and chromium. Pre and post oxidation treatments can be incorporated into the cycle to achieve certain benefits. Since the process does not require quenching to harden, it has the potential of producing a product that is more dimensionally stable and may not require any post-process finishing.

Fig. 5 – Horizontal retort nitriding furnace: "Traditionally, pit furnaces have been used for nitriding as they can accommodate larger load sizes and can be easier to seal as gravity helps keep the lid sealed; however, horizontal designs have gained in popularity in recent years."

This process is most commonly performed in batch equipment; while it is possible to use a continuous furnace, keeping the ends of furnace sealed to contain the atmosphere can be challenging. Traditionally, pit furnaces have been used for nitriding as they can accommodate larger load sizes and can be easier to seal as gravity helps keep the lid sealed; however, horizontal designs have gained in popularity in recent years (Fig. 5). In either case, the furnaces are usually a single-chamber design with the load sealed inside an Inconel or stainless steel retort.

To achieve a nitriding atmosphere, ammonia (not nitrogen) is used to supply the atomic nitrogen necessary for diffusion. At the process temperatures used, ammonia does not readily dissociate on its own; rather, it dissociates when exposed to a heated steel surface (iron acting as a catalyst) into atomic nitrogen and hydrogen. To control the amount of nitrogen available for nitriding, the dissociation rate of the ammonia can be measured with high dissociation rates (high hydrogen content) providing a lower nitriding potential and low dissociation rates (low hydrogen content) leading to more nitriding potential. The depth of the compound layer can be varied through control of the nitriding potential, with higher nitriding potentials producing a thicker compound layer.

For more precise atmosphere control, an ammonia dissociator can be used to provide gas to the furnace that has already been split to dilute the atmosphere with hydrogen to more quickly achieve a high dissociation rate in the furnace. The ammonia dissociator is a heated box with a small retort inside; the ammonia is passed through this retort that contains a catalyst to promote the dissociation of the ammonia, and the resulting gas mixture is cooled and then injected into the furnace.

Ferritic Nitrocarburizing

In the author’s opinion, just like with carbonitriding, ferritic nitrocarburizing (FNC) is named incorrectly as it is more closely related to nitriding than it is with carburizing. FNC is a process that is still mostly nitrogen-based but with a slight carbon addition as well. The added carbon helps promote compound layer formation, particularly in plain carbon and low alloy steels that do not contain significant nitride-forming alloys. This process is typically performed in a range of 1025-1125°F with cycle times much shorter than nitriding, typically 1-4 hours. The compound layer produced is usually much deeper than nitriding at 0.0005-0.0012”, with case depths reaching up to 0.025”, although in many applications a case depth may be difficult to measure. FNC is usually performed instead of nitriding in applications where the deeper compound layer is needed to increase wear resistance, but the added strength of a deep case depth is not as critical.

FNC can be performed in the same equipment used for nitriding, as long as a hydrocarbon gas is available to the furnace such as carbon dioxide or endothermic gas. FNC can also be performed in an IQ furnace using a mixture of ammonia and endothermic gas; for cooling, the parts can be oil quenched or slow cooled in a top cool chamber (if equipped).

Considerations

Case hardening processes are some of the most common heat treatments performed, but each process has its own unique needs. The table below provides a summary of the considerations that need to be made when selecting the optimum process. This list is by no means exhaustive; it is encouraged to work with a furnace manufacturer familiar with each process to help select the correct process and equipment needed.

The following transcript has been edited for your reading enjoyment.

Doug Glenn (DG):  We want to welcome Mr. Thomas Wingens who is from WINGENS LLC – International Industry Consultancy.  Thomas is no stranger to Heat Treat Radio.  Thomas, you’ve been here before and, in fact, you’ve got one of the more popular  Heat Treat Radio (as far as downloads).  It’s one of the ones we did several years ago, actually, on megatrends in the heat treat industry.  But, anyhow, Thomas, welcome back to Heat Treat Radio.

Thomas Wingens (TW):  Thankful to be back, Doug.

DG:  If you don’t mind, Thomas, let’s start off very briefly and give the listeners a brief idea of your history and your current activities in the heat treat industry.

TW:  My name is Thomas Wingens.  I am an independent consultant to the heat treat industry for 10 years now.  I have been in the heat treat industry for over 30 years.  As a matter of fact, my parents actually had a heat treat shop and I was born and raised above the shop.  We had various heat treat processes in our shop.  Vacuum heat treating we started in the early ’70s, but also atmosphere heat treating and nitriding.

Nitriding – I am also familiar with this, now for over 30 years.  I work with different companies and manufacturers on the one hand, but also other commercial heat treat shops (like Bodycote and Ipsen).  I am a metallurgist by trade.  I studied material science.

Today, I live in Pittsburgh, Pennsylvania with my family (not far away from you, Doug), and we really enjoy it here.

DG:  It’s very obvious you’ve got heat treat in your blood.  You were born and raised in Germany, but you’ve been here in the States for quite a few years now.  You’re well acquainted, and I think this is important, with not only the European technology that we’re going to talk about today – which is ferritic nitrocarburizing – but you’re also familiar with the U.S. market.  It gives you a good “in” in both of those markets and so a good perspective to share with our listeners.

This episode is basically going to just cover FNC, ferritic nitrocarburizing.  We want to start at the basic level and work down through a few questions for anyone interested in what it is, how to do it, and that type of thing.  If you don’t mind, FNC 101.

What is ferritic nitrocarburizing?

TW:  It is aligned with carburizing and nitriding into fusion treatment.  It is thermal process diffusion, not a coating.  As it is ferritic, it means it is not austenitic.  So, we’re not heating parts as high as we would do with carburizing or carbonitriding, which is more the range of 950 Celsius; nitriding in general is operated in a temperature range of 500 Celsius range and ferritic nitrocarburizing is in the 560 – 590 Celsius range.  We are not austenitic, and that makes a huge difference, especially when it comes to distortion.  We are treating with FNC parts which are ready to build in.  It is the final step, very often.  That is a huge difference.  We can do this because we do not experience any distortion.

DG:  So, you’re doing it at a lower temperature range, we don’t have to worry about distortion and things of that sort, and it is, more or less, the final step.

TW:  It is.  Like nitriding, the nitriding is taking place in the 500 – 540 Celsius, and usually the nitriding takes longer; it is up to 90 hours very often, so deep case nitriding is very popular for some applications.  The rise and the popularity of FNC is that we can achieve results very fast.  First of all, we are at elevated temperature versus nitriding as we are operating at 580 – 590 degrees Celsius.

But there is also the carbon content.  The additional carbon, in conjunction with the nitrogen, also accelerates the diffusion.  We are achieving faster diffusion layers with FNC than with nitriding.  So, shorter cycle times means lower costs and faster turnaround.  Instead of having 24 or 90 hours cycle times, we often have 4-6 hours.

DG:  Let’s do the comparisons again of the processes.  You’ve got nitriding which is probably the lowest temperature process, but it’s a much longer cycle.  If we’re moving up in temperature, probably ferritic nitrocarburizing would be next.  It’s going to be a much shorter cycle because you’ve got the addition of carbon as well, which is helping diffusion into the metals.  Then you’ve got nitrocarburizing or carburizing, both at much higher temperatures.  In fact, when you get to carburizing, you need to worry about distortion, I would assume, correct?

TW:  Exactly.  That makes a big difference because it is not the final step after carburizing or carbonitriding which is taking place at 950 degrees Celsius, or, if you go into a vacuum furnace with LPC, you can go even higher (up to 1000 Celsius).  Nevertheless, you’re in the austenitic field.  When your part is cooler when being quenched, you transform from austenitic to martensitic, and then you get distortion associated with quenching and the ensuing transformation.  That means you need to grind the parts to have finished parts.  That’s not the case with nitriding or nitrocarburizing or FNC.

DG:  As an example, can you list off some parts that typically go under FNC?  What are people typically ferritic nitrocarburizing? What types of parts?

TW:  Due to the fact that we have a couple of micron layer only, (that means you don’t have huge parts, for the most part), you are doing .3mm up to 3 or 6mm for deep case for windmill gears.  With the size of the part, usually the surface treatment layer is growing as well, so it really depends on the wear.

Nitriding certainly can be applied on large parts and it is done on very large parts, meaning 7 meter long extrusion screws and such; but it is because of the wear.  The work technique you have on a very unique surface layer with nitriding and nitrocarburizing is formed from friction.  When you have chemical wear, when you have fatigue wear, you get a couple of things.  One of them is you have compressive stresses that are holding up to some degree of fatigue, and then you have, of course, a high surface hardness of 1200 vickers.  You have a very high surface hardness and then if you have galling or pitting where metal on metal is wearing.  The nitriding layer is very supportive here.  But also, the chemical resistance is a very big factor.

A big part of the success of FNC is the combination with post oxidation.  That is a big part because the combination of ferritic nitrocarburizing with post oxidation leads not only to a mechanical strong surface with compressive stresses, it also has a very high corrosion resistance.  That combination is a wonder combination for several automotive parts.  A lot of components have been hard chrome plated in the past.  So you have several ball pivots, ball joints, in the car.  When you have an older car with chrome plated ball pivots, you maybe have heard an itchy noise, when the car makes a noise when you go over a curb or when you go up and down.  That is very often due to the fact that these ball joint pivots are corroded and were chrome plated.  That is a huge application.  That became the standard in the automotive industry.  Every ball joint is now FNC and post oxidized.

The other application that you see a lot is if you have a pneumatic trunk lift piston.  The piston, you remember, has been hard chrome plated so that you have the chrome finish.  You will see in a newer car, in the front hood, you have a gas piston that is FNC treated and post oxidized.  Everything that is exposed to corrosion, which are so many parts on the automobile, even the light building of the body.  This is something to mention.

[/blockquote]

All of these components I’m mentioning here are body parts predominantly and have nothing to do with electrification or with internal combustion drive trains.  They are not impacted by that, so we will not see any change here in the future.  A lot of under body components, where there is stone chipping and all the corrosion, people are tending to use FNC and black oxide because they can make it on thinner sheet metal part with compressive stresses so they have higher strength built in and they have the corrosion protection on top of it.  It’s a good combination.  And, of course, it’s virtually distortion free.  You may see that on some parts, due to very high compressive stresses, there is a buildup on the corners, but other than that, it is virtually distortion free and that’s a big, big plus of FNC.

DG:  That explains why it is growing in popularity.  I think that’s one thing you and I talked about earlier; there seems to be within the last, I don’t know, five years for sure, it seems like you’re hearing a lot more about FNC than you used to hear about.  Nitriding is still popular and carburizing is still popular, but you’re hearing a lot more about FNC, primarily because of the things you said.  Are there any other reasons, or is that primarily it?  Cost savings and good qualities.

TW:  If you look back, Doug, in the early days, in the beginning of the early nineties, I was running our nitriding department in our heat treat shop, and I had this little shaker bottle where it can determine the disassociation of ammonia and that determined the nitrogen potential.  The outcome was mediocre, to tell you the truth.  We did not clean the parts, we just put ammonia on it, and we had no way of controlling it other than the time and the temperature, so the outcome was a big variation. That’s why it was limited.  You could not find anything in the aerospace industry.  Nitriding was not accepted in aerospace at all.  Even in the automotive industry in the nineties, you did not find anything nitrided.  It was only used on tooling applications, and such.

But with the controls you have today, with the probes and sensors, you can determine everything, and you can see exactly what’s going on.  That has been a big factor.  There is the reproducibility of the layer you achieve and that is only possible with the good controls that you have and a better understanding of the process.

And, it is very important to mention, the cleaning of the surface.  There is no other heat treat process which benefits from good cleaning than nitriding and nitrocarburizing or FNC.  That makes a huge difference because you’re operating at a lower temperature and you don’t necessarily get rid of all the impurities and the ammonia gas, which, speaking of the process, really relies on the surface cracking of the material to dissociate in.  We have seen a huge impact if parts are not cleaned well on the different surface layers of FNC where we have missed the wide layer in total and such, so that is a big difference.

DG:  And the cleaning, I assume, besides just particles, I assume we’re talking about removal of grease and chemicals and things of that sort so that there can be good diffusion.

TW:  Exactly.  The surface has to be active.  The chips and the dirt to remove, that’s the easy part, but you have, sometimes, salts and residue from cutting and forming, especially the forming agents, sulfur phosphate, which are very hard to remove, especially for parts that are often FNC treated, like deep drawn parts or cheap metal components that are cut and there we see a big difference if they’re not cleaned well.

DG:  Run our listeners through a typical FNC process.  How does it happen?

TW:  I think it’s important to mention, as we haven’t done it yet, that we have three different processes.  We have salt bath nitriding or nitrocarburizing, gas, and plasma.  Each process has pros and cons.

The salt, there is a [cleaning] process or…QPQ, there are a lot of names out there for salt bath nitrocarburizing.  It is wonderful in that you just dunk it in, it’s quick.  The problem is the cyanide salts.  You have to carry it over, you have to clean it, you have to appropriately handle it, store it, and not everyone likes to do that.  Other than that, you have wonderful mechanical results with salt bath nitrocarburizing.

And then there is the plasma process.  The plasma is excellent for certain geometries, not so much for bulk.  You can place the parts in the furnace; it’s wonderfully clean and environmentally friendly.  Everything is good.  The problem is twofold: it is hard with bulk loads, it’s not as flexible on various parts and the other is with the post-oxidation, you cannot do it with plasma because it technically doesn’t work, so you need the… of gas nitriding in the plasma furnace to have the oxidizing part of the process, if you wish to go that route.

Having that said, the most widely accepted process is gas nitriding and gas nitrocarburizing.  Everyone knows that in pit furnaces this is one of the arrangements.  You put the parts in the furnace either vertically pit or modern now love horizontal arrangements, so if there is a loader you just have a batch.  Then you either purge with nitrogen gas or with a newer equipment that have a vacuum pump, so they have a vacuum purge system and instead of flushing with a lot of gas that draw a vacuum, they heat up the load and the convection to 580–590 degrees Celsius.  That can be done with so called “pre-oxidation process.”

Some people, especially if you have higher alloy chrome 4140 – “chrome alloyed” steels – they’re better to nitride if they are pre-oxidized on the way up.  Other than that, you would nitrocarburize ammonia gas, when you do gas nitriding, in conjunction with either endogas or CO2 gas.  Both, in combination, over a cycle time of 1 hour to 4 hours, soaking time and process time, and then you cool down with gas.  Not with the ammonia.  A lot of people make that mistake.  They heat up with ammonia or maybe even cool down with ammonia, but that is not correct.  Depending on, of course, what you’re trying to achieve, the best way is to flush it out because you have different disassociation processes going onto the surface and you have whatsoever surface combination nitrides if you don’t do it properly.

DG:  Are we gas cooling with nitrogen then?

TW:  You’re better off cooling with nitrogen.  Or you go interrupted cooling and then you oxidize on your way down, then you have this so called post oxidation.  You cool down to 300 – 350 C, and you have an FEO to layer which is dense, which is important.  You don’t want to have a flaky one or rough one, you want to have a dense oxidized layer as a surface and then you continue to cool.  That is basically the recipe of FNC.

DG:  I didn’t ask you before, and I should ask you: metals with which you can nitride or FNC, are they basically all steels?  Are there some steels you can’t do it with?  How about aluminum?  Titanium?  What can you do FNC with and what can’t you do it with?

TW:  I would say that nitriding is applied to a much broader spectrum of steels and even other alloys, let’s say.  People even do titanium and nickel alloys and try to put in nitrogen surface, calling it nitriding.  That is much broader.  FNC with nitrocarburizing is typically done with low carbon steels or carbon steels rather than high alloy steels.  That is why we have sheet metal parts very often.  So, low carbon or plain carbon steels.

DG:  And that’s maybe another reason, Thomas, why it’s become a more favorable process, right?  You can get some of the mechanical properties out with less expensive materials.  Is that safe to say?

TW:  Yes, that can be part of it.  But you should have a pre-hardened material, that’s important.  You need some carbon content in to have some hardness which sustains the high hardness of the surface.  It’s all prehard metals, for the most part.  Not necessary, but it certainly helps if you have some strength in the sub-strength which is supporting the hard layer.  It truly depends on your application.  But, you’re right: you can save on the materials to some degree and still get the mechanical properties that you’re looking for, especially in combination with the carbon.

DG:  Two final questions that maybe will help some of our listeners who are thinking about moving into the FNC direction.  The first question is, Who are the companies, and I know we can’t be exhaustive here, but who are some of the companies that actually manufacture this type of equipment that they could speak to?  And secondly, What are some of the things that companies ought to be asking themselves before they decide to go down the FNC rabbit trail, if you will?

So, first a list of companies if you have them.  We’ll try to be more exhaustive in our transcript of this.  If we miss any here, we’ll list them in the transcript.  But if you could rattle off a few that you’re comfortable with.

TW: There are the plasma people, that is RÜBIG GmbH & Co KG and Eltropuls and PlaTeG.  On the salt side, you have HEF Group, Degussa, and Kolene.  On the gas nitriding, you have Lindberg/MPH and Surface Combustion.  On the horizontal, very recently over the last 20 years, a very popular design is a horizontal vacuum perch retort nitriding and nitrocarburizing furnaces.  There you seen Ipsen, a German company called KGO, but also you have SECO/WARWICK with some proprietary designs (zero flow is also a good concept), and lately Gasbarre came into this business and Solar as well; they have the vacuum purge nitriding firms.

DG:  I want to back up a little.  On the salt bath companies you mentioned several, I also know Ajax Electric, also Upton Industries.  I don’t know if they do FNC units, but I’m assuming that they do.  There are a lot of other companies.

TW:  Salt bath is unique to salt.  There are only two, or three maybe, companies left in the world who supply these salts.  It’s more popular in Japan, by the way.  Anyway, it’s not as big as the gas process.

DG:  So, I’m a company thinking about maybe converting from some other surface hardening process over to FNC.  What kind of questions should I be asking myself?

TW:  It all starts, of course, with the product and the application.  Then you need to understand the wear and the corrosion methods.  That has to be well understood.   If that leads to FNC being the most suitable solution for this application, you need to understand the details of how you want to build up the surface layer, the thickness of your diffusion layer, the compound layer, the wide layer on the top and if you want to do post oxidation, so you will also need to do the oxide layer, which by the way, very often needs to be polished at the end, as well, to increase corrosion resistance.  These kinetics need to be well understood and the wear and what you want to achieve with this.

Then, of course, you have to see the design.  If you have sheet metal components which are cut, the cutting corner usually receives a higher layer and then the corners themselves that built up due to stresses, so there are a couple of minor things that need to have attention.  Then, of course, you need to have an expert who really refines the process, and that has to be done in conjunction with good controls.  There are two or three companies in the market.  UPC is one of them.  Oh, I forgot to mention Nitrex, a big brand.

DG:  UPC is part of Nitrex, but they also do the process.

TW:  Right.  Very important.  Somebody who really understands the nitriding and the control part of it.  UPC Marathon, they have very good controls.  SSI also has the probes.  There is STANGE in Germany as well.  You have two or three companies which have good knowledge in the controls and the probes and how to control this nitriding process.  Then you can build up your desired layer system.  In the layers, you have a diffusion, then you have a compound, a white layer, and then maybe you have an oxide layer on top and that needs to be well understood.  And, of course, as mentioned before, it is essential to have  parts cleaned thoroughly and if you maybe need a polishing afterwards.  Then, of course, how you put them in the furnace (placement) so that the gas can uniformly penetrate the parts.  These are the essential things.

DG:  There you have it, folks.  That’s FNC 101.  Those are the basics in ferritic nitrocarburizing from Thomas Wingens.  Thank you, Thomas.  I appreciate it very much.  I know that if people have questions, you, specifically, would be more than happy to help them out.  The company again is WINGENS LLC – International Industry Consultancy.  Thomas, www.wingens.com.

TW: That’s it!
