Provided is a composite material for sliding members which comprises a titanium carbide matrix and graphite particles excellent in crystallinity which are uniformly dispersed in the titanium carbide matrix. This composite material has self-lubricity and high wear resistance together with the excellent properties of titanium carbide such as high strength, high hardness, high melting point, low specific gravity and high electrical conductivity.

Composite materials for sliding members

A sintered non-oxide ceramic composite high in density, high-temperature strength and toughness and having optionally and widely changeable electrical conductivity is obtained by compacting and sintering a mixed powder comprising 5-95% by weight of at least one compound selected from titanium carbide, nitride and carbonitride, 0.1-5% by weight (based on silicon carbide) of boron or boron compound in terms of boron, 0.1-5% by weight (based on silicon carbide) of carbon or carbon compound in terms of residual carbon and the balance of substantially silicon carbide.
