FIELD: machine building.
SUBSTANCE: invention relates to a sliding element, in particular to piston ring, with a wear-resistant coating, and also to cylinder piston group. The sliding element has a wear-resistant coating containing in a direction from inside out CrN layer , Me(CxNy) layer, where Me represents a tungsten, chrome, titanium or silicon, meanwhile x and y are within a range of 0-99 of atomic percents, except for the layer of clean chrome, and the layer of diamond-like carbon (DLC-layer), which consists from lower metal-containing DLC-layer and upper DLC-layer, not containing no metal, meanwhile the hardness of CrN-layer amounts 1100-1900 HV. The cylinder piston group contains a named sliding element and iron-based companion working element as the barrel or cylinder liner of the internal combustion engine.
EFFECT: necessary longevity and power in diesel or petrol engine are ensured, in which the proposed piston ring or cylinder piston group are used.
