The paper shows that achieving only high heat and corrosion resistance of the developed multicomponent metal compositions and ceramic materials is not enough to provide the required protective properties of the blade apparatus of modern gas turbine installations. The problems of matching layers in multi-layer coatings in terms of KTR values, diffusion interaction and others performance characteristics have become very important. Systematic long-term research has allowed us to determine that for these purposes, the most acceptable compositions are those that crystallize to form eutectic structures based on Nickel and/or cobalt, in which, due to changes in the content and concentration of alloying elements, it is possible to obtain a different combination of plasticity, thermal fatigue resistance under conditions of cyclic oxidation and gas corrosion. The best results were obtained when using the developed composition of the Ni-22Cr-16Al-1Y composition, it is sprayed using a plasma method using a granular conglomerated powder prepared using a specially developed technology. To overcome the disadvantages of plasma coatings and, first of all, low thermal stability at elevated temperatures, it was proposed to apply a barrier layer to the boundary of the alloy-plasma coating in the form of a thermodiffusion aluminide layer of the composition 28Al-2Si-1PZM. A sprayed ceramic coating of the composition (ZrO2 + Y2O3) was chosen as a heat-protective surface layer. As a result, a combined three-layer heat-resistant coating was developed, which was applied sequentially using various technologies. The first thermal diffusion layer with a thickness of 40-55 microns is located on the border with the base alloy and provides high heat and corrosion resistance, as well as diffusion stability of the entire coating as a whole. The second plasma metal layer with a thickness of 110-115 microns provides high thermal stability of the coating and good adhesion of the ceramic outer layer to the metal surface. The third outer ceramic layer with a thickness of about 50 microns is heat-protective and protects the surface of the blade from overheating. Comprehensive laboratory, bench and field tests on the blades as part of the product allowed us to introduce the regulations and developed technical process into serial production.
