FIELD: technological processes.

SUBSTANCE: invention relates to a method of applying a composite electroconductive solid lubricant wear-resistant coating on kinematic contact pairs from copper alloys and can be used in aircraft industry, machine building and other fields. Method comprises pulsed magnetron sputtering of cathode from copper grade M1 with annular concentric grooves, in which molybdenum disulfide powder is pressed for ion-plasma deposition of layer of Cu-Mo-S system, containing molybdenum disulfide, doped with copper, and having a fibrous-globular structure consisting of a mixture of nanograins of the Chevrel phase Cu₂Mo₆S₈ and nanocuboids of pure copper. In another version of the invention, a copper layer is applied after ion-plasma deposition of the said layer of the Cu-Mo-S system by pulse magnetron sputtering. Then said layers are applied by alternation until reaching three layers of Cu-Mo-S system with thickness of not less than 60 mcm with intermediate layers of copper with thickness of not more than 1 mcm to obtain a composite coating with a total thickness of not less than 180 mcm.

EFFECT: obtaining electroconductive solid lubricant wear-resistant coating on kinematic contact pairs from copper alloys, operating under vacuum conditions, and increasing their service life by at least 200 times.
