Helicopter engine erosion has become a severe problem in S. E. Asia because of extensive operations in sand and dust. Hard coatings offer a potential means of increasing the life of aircraft gas turbine compressor rotor blades and stator vanes. Two proprietary erosion resistant coating systems--Texas Instruments, Inc. TI-KOTE C and Union Carbide Corp.s impregnated flame sprayed carbides, were selected on the basis of preliminary laboratory and engine tests as the two most promising systems for doubling compressor airfoil lives. An Air Force Sponsored program to evaluate the applicability of these systems for 403 stainless steel and AM355 production hardware was undertaken. The program was divided into three phases Coating optimization Process scale-up and Engine qualification and environmental tests. Author
