A complex coating consisting of three layers, i.e., a gas-circulation coating and a two-layer ion-plasma coating with an internal Ni − Cr − Al − Ta − Re − Y layer and an external Al − Ni − Cr − Y layer for protecting single crystal turbine rotor blades from high-temperature oxidation is considered. The fine structure and the phase composition of the complex coating and of the reaction zone of interaction with single-crystal alloy ZhS36-VI after high-temperature holds in a range of 1050 − 1300°C for 1–1000 h are studied.
