“…To conduct experimental studies, samples were made, which were the rings of steel grade 40G with an outer diameter of 55 mm, inner -35 mm and a width of 10 mm. Plasma surfacing was performed along the outer diameter of the sample with the powdered material composition [16]. In this case, the constant parameters during plasma surfacing were: -plasmatron vibration amplitude -𝐴 = 18 mm; -plasmatron oscillation frequency -𝑣 = 80 min -1 ; -plasma gas flow rate -𝘨 1 = 1.5-1.8 l/min; -conveying gas flow rate -𝘨 2 = 10-12 l/min.…”

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.
