<p>A nanolayered coating, having a thickness of less than 100 nm, comprising nanolayers of: (i) TiN; and (ii) CrN, MoN, AlN, or AlN and CrN. The coating has an erosion rate, according to ASTM G76, at a particle velocity of 60 m/ s and an impingement angle of 90°, of no greater than 4.0 x 10-3 mm3/g. Also provided is a monolithic TiAlN coating. Such coatings may be useful for ero sion protection of aircraft or gas turbine components; or wear protection of gears, cutting tools including machine cutting tools and surgical cutting t ools, or other metallic surfaces.</p> |
