FIELD: machine building.
SUBSTANCE: invention relates to sliding element, particularly, to piston ring with coating on at least one sliding surface and to method of making of said sliding element. Said sliding element, particularly ICE piston ring has the coating on at least one sliding surface in direction from inward to outward. Said coating comprises metal-bearing adhesion ply and that of diamond-like DLC carbon ta-C type at least 10 mcm in depth. Tetrahedral carbon ta-C ply contains sp3-ibridised carbon atoms in amount of at least 40 at. % and hydrogen in amount of at least 0.5 at. %. Note here that the content of sp3-ibridised carbon atoms in outer 1-3 mcm plies is decreased.
EFFECT: better combination of friction and wear resistance factors.
