Abstract
The investigation of microstructure and properties of Ni-base alloy ha s been carried out after various coatings (one- and multilayer) being deposited by EB PVD method and recovering heat treatment being fulfill ed. The optimal conditions of recovering heat treatment make it possib le to retain the entire complex of mechanical properties at the level typical for the alloy without coating. The tests for cyclic strength o f the blades with coatings have shown the advantage of coatings with a n external ceramic layer in comparison with metal coatings.
