This paper describes the friction and wear properties of carbon/silicon carbide composites in comparison with that of porous silicon carbide and dense silicon carbide. Tests were conducted in ambient air, using a pin-on-disk friction test apparatus. The friction and wear properties of these materials varied according to the combination of pin and disk materials. The carbon/silicon carbide composite containing the largest carbon volume(about 40 vol%)showed the lowest values of friction coefficient and specific wear among all the investigated materials. In addition, it also showed a stable behavior with respect to sliding velocity. The friction and wear mechanisms of these materials were discussed according to the morphology of the worn surfaces observed by scanning electron microscopy(SEM).
