Abstract:
The present invention concerns a friction piece (10) suitable for operating in a lubricated medium at a temperature higher than 200° C. The piece (10) comprises a metal surface (12) and an external coating (14) composed of tungsten carbide doped with nitrogen WC(N) with an atomic ratio of nitrogen between 5 and 12%. The invention also relates to a mechanical system (1) comprising such a piece (10). The invention also relates to a method for implementing such a piece (10).
