“…The most optimal in terms of obtaining high elastic properties is the plasma surfacing mode, at which 𝐼 = 170 A , U = 48 V , 𝑉 = 0.14 m/min . At the same time, the powdered aluminum content in the composite powder material was 8% [28]. It should be noted that the highest hardness of the surfaced coating, which was 𝐻𝑉 = 580 was obtained in this plasma surfacing mode.…”

At present, a strategically important task of technological independence of Russian industries is restoration of worn-out parts of machines and equipment by plasma methods based on the use of coatings of different functional purpose. The purpose of this study is to solve the actual problem of choosing the rational modes of plasma coating in the process of restoration of worn parts, subjected to intensive wear in the operation process. To solve this problem, the experimental studies of the elasticity characteristics in the plasma-deposited coatings were carried out. The study results allowed determining the most optimal range of rational modes of plasma coating deposition in terms of obtaining high elastic properties of plasma coatings as the key stage of resource-saving technology for restoration of worn parts of machinery and equipment.

“…Most of the works are devoted to the first and second methods of searching for optimal modes of plasma deposition of protective and wear-resistant coatings [14,26,27]. In this case, the first method is laborious due to the need for a large number of experiments, the second method is limited by the poorly understood process of particle motion in plasma and the absence of experimentally verified criterion dependences describing the heat transfer of particles with the plasma and the lack of data on the effect of the introduced particles on the parameters of the plasma jet.…”

The influence of various design and technological parameters of the process of plasma deposition of coatings on their quality is considered. In the process of research, regularities were revealed and relationships were established between the factors and criteria of technological processes, which make it possible to solve optimization problems when developing technological recommendations and improving the methods of applying plasma coatings. The results of the research are the obtained mathematical models that can be applied to analyze the influence of individual factors, as well as their combination on the quality indicators of the process of forming coatings with given physical and mechanical properties.
