FIELD: machine building.
SUBSTANCE: present invention relates to friction parts, operating in environment with lubrication, containing friction modifier, wherein, at least, one of parts is covered with coating, wherein friction modifier is MoDTC, coating is different from DLC and for, at least, one part is chromium nitride, wherein chromium nitride is present in crystallization with NaCl-type structure with microhardness of 1,800+/-200 HV. Disclosed invention also relates to use of friction parts.
EFFECT: technical result of present invention is combination of chrome nitride and MoDTC properties with provision of considerable reduction of friction coefficient without reducing hardness.
