Austenitic type 304 stainless steel was ion-nitrided and subsequently ion-plated with CrN or CrNi-N whose Ni content was varied from 11 at% to 50 at%. The ceramic film of CrN coated onto the pre-nitrided steel showed the good wear resistance even under a heavy load. Further, the CrN film with a thickness of 10 μm showed the minimum wear loss among the CrN films of 319 μm. As for the cermet films of CrNi-N composed of Cr<SUP>*</SUP>N and Ni, the CrNi-N film with Ni content of 11 at% coated onto the pre-nitrided steel showed the best wear resistance compared with the CrN film or CrNi-N films with high Ni content. Its good wear resistance was maintained even at the thick film over 20 μm, being different from the tendency of CrN film.
