Abstract

Describes the application of the technology of applying erosion-resistant and fretting-resistant ion-plasma coatings to protect compressor blades of VT8M-1 alloy from erosion wear and fretting, presents the results of tests of compressor blades for erosion resistance and vibration fatigue, samples of VT8M-1 alloy for fretting wear, multi-cycle fatigue and long-term strength, metallographic and metallophysical studies. It has been established that multilayer coatings TiN/CrN and Ti+TiN increase, respectively, the erosion resistance of the feather and the resistance to fretting wear of the locking part of titanium GTE compressor blades while maintaining their fatigue strength.
