FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy, namely, to the sliding element in an internal combustion engine. The sliding element of the internal combustion engine includes a base and a coating produced by means of thermal sputtering of a powder containing, wt %: from 55 to 75 Cr, from 3 to 10 Si, from 18 to 35 Ni, from 0.1 to 2 Mo, from 0.1 to 3 C, from 0.5 to 2 B and from 0 to 3 Fe.
EFFECT: improved tribological properties of piston rings.
