The friction and wear characteristics of hot pressed TiN and TiC were examined in dry and wet atmospheres of oxygen and argon using a pin/disc type friction tester. In an atmosphere containing oxygen or humidity, for both TiN and TiC, a surface film composed mainly of titanium oxides and/or their hydrates were produced during runs. The formation of the surface films resulted in suppressing brittle fracture of the rubbing surfaces and reducing wear amount by a factor of 4 to 30. TiC has high ability to form TiO2 with low shear strength compared to TiN. In contrast, TiN is expected to keep a TiO2 film firmly through TiO formed on the TiN surface as the substrate of TiO2, since a lattice constant and interatomic distances of TiN are nearly equal to those of TiO. Therefore, a low friction of about 0.1 was attained with a combination of TiC pins and TiN disc.
