The main features of the process reflecting product surface heating during low-temperature plasma treatment have been established, and the necessity of managing this process has been substantiated. A control method has been developed that makes it possible to determine the moment of termination of the plasma effect on the product surface using a logistic curve as a data model on the temperature recorded outside the zone of thermal plasma effect (lagged temperature).

Basic features of combined-discharge low-temperature plasma formation around the surfaces of complex-contoured metal units are considered. It is shown that it makes the possibilities for synthesis of hardened high-durable coatings of hard tools appropriate for material processing in extreme load-temperature conditions. Experimental study of the coating formation was carried out in combination with the analysis of emission spectra of a low-temperature plasma cloud. Some practical examples of the coating applications are presented.
