The nonlubricated sliding wear of SiC–B4C–Si cermets against a diamond indenter was studied. The cermets containing 2, 5, 10, and 20 wt.% of Si were fabricated by both conventional sintering and spark plasma sintering (SPS) techniques. It has been observed that wear depth, volume of the wear debris, and wear rate increases with increasing applied load for both cases. Minimum wear depth and lowest wear rate was obtained for the cermet containing 10 wt.% Si. Three-body abrasion is the main wear mechanism which results in surface delamination, and formation of grooves and cavities on the damaged surface.
