[PROBLEMS] A conventional mechanical member has disadvantages inferior in wear resistance, seizure resistance and corrosion resistance. In the nitrogen-containing Cr film of A present invention, it allowed to intersperse Cr X N Y crystals Cr film containing nitrogen containing chromium atom and a nitrogen atom of 50-1 100 atoms per 50 to 99. In addition, a coating is provided on the surface of frictional wear parts such as machine members, particularly motorcycles, motorcycles, and automobiles. [Selection] Figure 1 |
