Aerospace/Airline Forum: Titanium Nitride Coatings are Ideal for Aerospace Applications

Titanium nitride coatings (TiN) can be applied to anything from dies to pumps to sporting goods. However, they are especially ideal for aerospace applications and coatings supplied by the company have found homes on jet engine components on just about every space shuttle and elbow joints on the International Space Station. Their are many. For example, they exhibit extreme hardness characteristics; TiN supplied by the company exhibits 2800 HK¹ (Rockwell C) while the new AlTiN coating exhibits 400 HK¹ (Rockwell C). According to a company representative, after the parts undergo a vacuum physical vapor deposition operation, a high-vacuum proprietary process is used to remove macroparticles.

The company can ionize over 95% of the coating ions for tighter seven- to eight-molecular layers. The tightly packed ions create a harder surface. Parts that are coated using TiN do not experience galling or fretting and exhibit excellent corrosion resistance.
