«Structure and Properties of Piston Rings with Ion-Plasma Multilayer Nanohardening»
661–678 (2019)

PACS numbers: 62.20.Qp, 62.23.Kn, 81.15.Jj, 81.40.Pq, 81.65.Lp, 81.70.Jb, 82.80.-d

A method and application parameters for hardening of oil-scraper piston rings by multilayer ion-plasma TiN/CrN nanocoating are proposed. An increase in the microhardness of piston rings by 143 times relative to serial rings is shown. An increase in the wear resistance of piston rings by 12 and 15.7 times is achieved at sliding speeds of 1 and 1.3 m/s, respectively. The chemical-composition study of friction surface of the rings with hardening is carried out. Structurization of the adjacent surface of both variants of rings due to cyclic effects during friction is revealed. A method for estimating diffusion of the Fe rings towards the strengthening multilayer coating is proposed.

Keywords: piston rings, ion-plasma multilayer nanocoating, wear, microhardness, X-ray microanalysis, diffusion
