摘要：

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