Abstract: The article presents the results of a study of the influence of plasma jet parameters on the characteristics of multilayer composite coatings based on nickel-chromium, nickel-chromium-aluminum-yttrium and aluminum and titanium oxides. In the process of obtaining sprayed wear-resistant layers from the developed powder materials, there are a large number of process factors that affect the properties of the created protective coatings. The main factors are the speed of the devices for moving the plasma burner or substrate, the distance used for spraying, the consumption of the plasma-forming and transporting gases used, the consumption of the material used for spraying, the power supplied, depending on the voltage and current of the electric arc of the plasma torch. Optimization was carried out on the basis of obtaining the maximum utilization factor of the powder. The results of studies of the morphology of the formed coatings performed using scanning electron microscopy are presented.
