Wear resistance coatings of nickel alloys obtained by supersonic plasma torch

Abstract

The research results of coatings of nickel alloys deposited using supersonic atmospheric-plasma spraying are presented. The main feature of the work carried out is that the plasma flow is charged by powder material using the powder ring injector designed by authors. The ring powder injector unit is equipped by a gas dynamic focusing system that makes it possible to ensure the conditions of creating coatings which are not subject to wear and tear under abrasive friction.
