CVD Tungsten Carbide and Titaniutm Carbide Coatings for Aerospace Components 890933

Aerospace components are often exposed to adverse environments that can lead to wear and decreased performance. Air Products is actively pursuing commercial applications of ceramic coatings for improving the wear resistance and tribology of stainless steel components such as compressor blades and ball bearings. This paper reviews two coating systems: a proprietary erosion-resistant tungsten carbide (CM-500L®) coating system and a licensed wear-resistant titanium carbide coating, which has been qualified for use in several critical navigational gyroscope systems in the U.S. and European aerospace Industries. Both have demonstrated performance and applicability superior to other protective coatings.
