Changes in Nanohardness and Wear Resistance of Piston Rings by Varying the Parameters of Plasma Coating Deposition

Abstract

The production of piston rings, the main failure of which is wearing of working surfaces, takes a considerable place during various parts producing. Therefore, large attention is payed to the problems of wear resistance improvement of pairs of friction of piston rings surfaces. The creation of combination of high hardness with high plasticity is real in a heterogeneous alloy. The problem of developing a method for increasing the wear resistance of piston rings seems to be a topical issue.
