There seems to be no limit to what heat treated titanium alloy products can do -- just listen to the name: "titans." However, its poor tribological performance means that a surface treatment is necessary in most applications.

This best of the web article shares a quick technical run-down of all you need to know about plasma/ion nitriding of titanium alloy products with guidelines and graphs to show you the way.

An excerpt:

At the moment, nitriding is the most common and rational diffusion treatment which can be used for all-over surface hardening of titanium products. Nitrided titanium has a gold/yellow color of the TiN nitride enhancing attractiveness of the treatment in many applications.

Aerospace Manufacturer Acquires Plasma Nitriding & Annealing Systems

/ AEROSPACE HEAT TREAT, AEROSPACE HEAT TREAT NEWS, FEATURED NEWS, NITRIDING NEWS

A leading aerospace engine and components company based in Mobile, Alabama recently partnered with a global heat treat specialist to improve its nitriding and annealing processes with plasma nitriding technology.

Continental Aerospace Technologies™ (formerly Continental Motors), which is recognized for manufacturing piston engines for small aircraft, sought to improve its nitriding systems with high ammonia emissions and turned to RÜBIG Industrial Furnaces, an Austrian metal hardening company. RÜBIG supplied two “EVEREST 100/180 Duo” plasma nitriding and annealing furnaces, as well as a cleaning solution. The equipment provides independent multi-heating and cooling zones and the Micropuls® technology.

Heat Treating Toughens Wind-Turbine Components Against Extreme Conditions

A heat treating process surfaces as one of the most effective methods to prolong the lifespan of wind turbine components. Turbine shaft bearings, planetary gears, and rotating shafts operate under extreme conditions, and the demand for taller and larger wind turbines limit the options available to manufacturers and operators seeking protection against wind, weather, fatigue, and overall wear and tear.

Plasma nitriding was recently found in tests to exhibit “one-fifth the roundness deviation and seven times better planarity than gas nitriding on a two-meter diameter ring gear,” said Dr. Florian Rovere of Oerlikon Balzers, a supplier of surface technologies for metal processing industries in North America.

“Plasma nitriding has the advantage of making the treatment more precise by minimizing warping and distortion while providing a higher load-bearing capacity,” notes an article published in Windpower Engineering & Development.

“It is . . . an important discovery for the service life of a system where enormous forces are at work,” said Rovere.
