PURPOSE:To prepare a hard coating film composed mainly of Cr, having excellent sliding characteristics such as abrasion resistance and seizure resistance and exhibiting excellent initial conformability. CONSTITUTION:The sliding part is produced by coating a substrate with a coating film composed of Cr, an M group (M is Ti, V, Zr, Nb, Mo, Hf, Ta, W and/or Al), N and O and having a compositional ratio of the metallic elements M/(Cr+M) of 1-55 atom % and that of gaseous elements O/(N+O) of 5-80 atom %. |
