摘要：
The technology of ion-plasma hardening of oil-scraper piston rings of D100 diesel engine by multilayer TiN/CrN composition is proposed. Comparative tests for friction and wear of the piston rings have been carried out and the multiple increasing in wear resistance of the rings with ion-plasma coating is shown. An estimation of the change in their microhardness before and after the tests was performed. The nature of the change in the composition of coatings: both in the initial state and during operation by local micro-X-ray spectral analysis was established. A method for estimating the effective thickness of coatings, which is protected by a patent, is proposed.
