Heat Treat Today’s Meet the Consultants: Daniel Kay

Heat Treat Today recently unveiled its Heat Treat Consultants page in the October 2018 print edition (available in digital format here) and at FNA in Indianapolis, Indiana. We offer this comprehensive listing of heat treat industry consultants as part of our efforts to help minimize the effects of heat treat “brain drain.” With so many heat treat brains growing older, the expertise that once used to reside inside of manufacturing operations is dwindling. Where, then, do manufacturers with in-house heat treat departments go when they need heat treat answers?

Turn to Heat Treat Today and our comprehensive list of heat treat industry consultants, which we will introduce to you one by one in this occasional feature, “Meet the Consultants”. There is no more comprehensive list of heat treat consultants. Learn more about Dan Kay of Kay and Associates, and then click through to the page to read more details about each consultant. We are adding more regularly. Contact them directly, or call us and we’ll introduce you to them. Whether it’s a technical process question, a safety concern, a compliance issue, or a business related question, one of our heat treat consultants will be able to help. If you are a consultant and would like to be listed, please contact Doug Glenn.

Briefly:

Dan Kay has been involved full-time in brazing engineering for more than 45 years and has been operating his own brazing consulting and training business since 1996, regularly consulting in areas of vacuum and atmosphere brazing, as well as in torch (flame) and induction brazing. Dan has become known worldwide as an excellent seminar leader, trainer, speaker, and well-versed brazing auditor, traveling all over the world not only providing consulting and problem solving but also teaching brazing seminars and conducting in-house brazing-training programs. Numerous publications include his articles on the subject of brazing; in addition, he is a regular contributor to several online resources, including Industrial Heating, VAC AERO, and the Heat Treat Forum. Dan’s extensive knowledge and experience in brazing have also proven useful over the years when companies are seeking an “Expert Witness” in legal matters, enabling clients to bring about resolution to their legal issues, usually without having to go inside a courtroom.

Dan Kay on Brazing Stop-Off Materials

Heat Treat Today will soon be launching Heat Treat Consultants, a resource that offers the most comprehensive listing of heat treat industry consultants. An example of the type of exchange we anticipate will result from this resource is provided below.  Click the link above for a sneak peek at our inaugural list of consultants and more information about contacting one of the experts listed.

Mike Dascoli, general manager of County Heat Treat in Millbury, Massachusetts, asked our publisher, Doug Glenn, about a product the company had used previously, “an alumina oxide powder to coat graphite fixturing plates . . . in our vacuum furnaces to stop off against braze alloy run off and eutectic melting.” Doug queried whether it was aluminum brazing or more conventional brazing of stainless or other metals and Mike specified, “No aluminum brazing . . .  used to be gold/nickel, silver alloys. Here at County, I am just looking to introduce some options. I remember we would mix the powder with the acetone and paint it on the carbon plates. Acetone evaporated quick and the powder was left behind. For us now, it’s more about a layer against eutectics when heat treating.”

Doug brought in one of Heat Treat Today‘s consultants, Dan Kay of Kay & Associates Brazing Consulting & Training Services, to assist in hunting down the answer to Mike’s question.

Dan Kay:

Hi Mike —

Yes, there are a number of brazing filler metal (BFM) manufacturers who also produce and supply brazing stop-off materials that can be painted onto graphite surfaces such as you mention in your note to Doug Glenn.  Here are just a few:  Surface Flow Technologies (Div. of LSN Diffusion Int’l) in Michigan, Wall Colmonoy Corp in Michigan, Vitta Corp in Connecticut, and Wesgo Metals (Div. of Morgan Advanced Materials) in California are some of the primary ones.  

Stop-off materials come in different colors, the coloring of them being merely to identify its manufacturer, since all stop-off materials use metallic oxide materials to create their “stop-off” capabilities, and all these oxide powders are essentially white, to begin with.  Thus, to differentiate the various stop-offs they began to color them so that people would learn to associate green stop-off with company A, pink stop-off with company B, red stop-off with company C, etc.

White stop-off products are essentially the weakest of all the colored stop-offs out there and are primarily aluminum-oxide products in a paint-like consistency.  The binders/gels used to make the stop-offs vary considerably from manufacturer to manufacturer are proprietary, and you’ll not get any of them to actually tell you about all the ingredients in them.  People are often surprised to hear that a product such as Phillips Milk of Magnesia, available in lots of stores or pharmacies, is actually a decent stop off (magnesium oxide) for a number of applications.

But you are correct to say that you can make your own in many different ways by merely mixing some aluminum-oxide powder, or titanium-oxide powder, etc., in with a variety of quick-drying solvents, perhaps also with a thin acrylic type cement to give it adherence, paint it onto graphite surfaces, and after evaporation you would be left with an adherent layer of that protective oxide barrier, so that it prevents direct contact of a metal (especially any iron-containing metals) with the graphite, since an iron-carbon reaction is to be avoided.  

I’d be happy to assist you further with this, if you have additional questions, since I’ve had much direct manufacturing experience over my 45+years in the brazing world, a lot of it involved in making BFMs, brazing stop-offs and cements, etc., and am pretty much aware of the companies today who make and supply such materials.

On my website at http://www.kaybrazing.com, you will see a tab on the homepage that shows “Brazing Suppliers”. By clicking on that tab you can see a listing of the different companies who produce these materials, and in that tabular section the name of each company (such as those I mentioned above) is a hotlink that will bring you directly to that company’s website so that you can search it for a specific type of product that you might desire.  It part’s of the service that I want to provide to users of my website.  I hope you will find it useful.

Let me know how I can help you further.

Best regards,
Dan
