Essay

Reasons of cases of anomal wear of piston rings of the forced engines are analysed and the limits of application of serial chromic coverages are set. Influencing of process of causing of galvanic and plasma coverages is studied on epure of radial pressure of ring. It is shown that finish treatment of the prepared piston ring with plasma coverage on a work surface allows to promote wearproofness the ionic nitridings or laser irradiations both working and butt end surfaces.
