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.

Key words: vacuum-arc coating, nanohardness, nanostructural coatings, wear resistance, piston rings.
