Development of Thick, Hard Coatings for Erosion Protection Applications

J. Arps, R. Wei, Southwest Research Institute, San Antonio, TX

View in WORD format

Summary: Southwest Research Institute has been developing thick and hard nano-composite coatings (>30 micrometers) for improved erosion resistance of jet engine compressor blades and other applicaitons. The technology used is plasma enhanced magnetron sputter deposition. Several nanocomposite systems have been studied and evaluated inclusing (Ti,Si,Cr,Zr)-(C,N). The microstrutual data and erosion data will be presented.
