Abstract: The article presents the results obtained as part of a study of the influence of technological characteristics of compression plasma flow processing on the quality indicators of composite coatings based on nickel-chromium-aluminum-yttrium materials with aluminum and titanium oxides. The resulting temperature gradients and alloying of the source material during the processing often lead to structural and phase transformations in the surface layers of the applied materials and, accordingly, to a change in their technological properties: hardness, wear resistance, heat resistance, adhesion strength, etc. Completely new opportunities for modification. properties of coatings and a significant improvement in the resulting performance characteristics is achieved by the use of compression plasma flows, which are generated by quasi-stationary plasma accelerators. The issues of hardening plasma coatings from the developed materials using high-energy processing methods are considered in detail. The characteristic technological parameters of the hardening treatment of formed plasma coatings have been studied and optimized. By changing the used technological characteristics of the process of processing pulses of compression plasma flow, we changed both the distance under the influences and their number. The number of pulses significantly affects the thickness of the treated layers. The total number of pulses should create a melted coating with high strength characteristics over the entire thickness.
