Erosion resistance of a combined multilayer coating protecting critical parts of modern gas turbine engines
Comprehensive studies of the chemical composition, microstructure, and thickness of a combined multilayer coating on a heat-resistant nickel alloy are presented. The distribution pat-tern of chemical elements over the coating thickness for all the layers, namely the inner aluminosili-cated layer, the plasma sublayer, and the outer heat-insulating layer, has been established. Surface roughness was determined at all the stages of coating application and after testing. The results of comparative tests of corrosion-erosion resistance and resistance to burn-through of a diffusion aluminosilicide coating, a two-layer heat-insulating coating, and a combined multilayer coating are presented. High heat-shielding properties of a combined multilayer coating on a heat-resistant nickel alloy have been discovered.
