Friction and wear tests were conducted to determine the tribological properties of hard materials, such as coating films and sintered ceramics, versus several types of industrial metals.<br>TiN and CrN films deposited on flat tungsten-carbide substrates by ionplating were selected as coating film specimens. Si<sub>3</sub>N<sub>4</sub> and SiC as sintered ceramic specimens. Each specimen was slid reciprocally against metal balls (SUJ2, SUS304, Ti-6Al-4V, Ti, and Al). After sliding experiments, specimen wear and metal transfer were studied.<br>SiC showed the lowest friction coefficient in this study. Sintered ceramic specimens wore normally. In contrast, peeling wear occurred on the TiN film against SUJ2, SUS304, and Ti-6Al-4V. Coating films, especially CrN, have better wear resistance than sintered ceramics. Mating materials (metal balls) wore heavily in sliding against coating films, presumably the sub-micro-scale surface roughness of coating films affected the wear.
