Ion-Plasma Coatings for Protection and Reconditioning of Precision Friction Pair Parts

Abstract

There is elaborated a technology of reconditioning of precision pair parts, which are manufactured from metallic materials – valves, plungers and injectors of vehicle fuel pumps and hydraulic motors, water power devices, etc. The technology stipulates the creation of a special coating, which is deposited applying the method of ion-plasma sputtering and possesses some improved performance characteristics (increased wear-resistance, oxidation and hold resistance, corrosion resistance and decrease of friction coefficient)
