Equipment and technologies of air-plasma spraying of functional coatings

Abstract

This article presents a short description of the DC plasma torch "PNK-50" structural features (ITAM SB RAS, Novosibirsk) used for spraying of functional coatings with powder materials as well as gives the results of thermophysical and technological studies of spraying regimes. We present preliminary results of the plasma torch supersonic modification development and the results of industrial approbation of the plasma torch and of multi-purposes functional coatings deposition processes.
