Ti-based composites containing fine diamond powder were fabricated using spark plasma sintering. 'We evaluated their friction and wear properties with a reciprocating friction tester in water and air using an Al_2O_3 mating ball. The addition of diamond to the matrix considerably decreased the composite's friction in water as well as ambient air. The specific wear rate of composites was negligible in water and air, although a little wear of the mating ball was existed.
