The unlubricated sliding of diamond and tungsten carbide against nickel-ion implanted titanium diboride have been investigated. The diamond sliding is characterized by low friction (<0.02) and the formation of a carbon-bearing debris layer on the wear path. Tungsten carbide slides on TiB/sub 2/ with a stick slip motion and friction values ranging from 0.2 to 1.0, and forms wear grooves. The effect of implantation on sliding wear rates have been explored by sequential wear tests which indicate a limitation of the wear groove depth to that of the modified lattice. 14 refs., 8 figs., 2 tabs.
