Popis: The dry sliding behavior of Ti 3 SiC 2 against itself and diamond was investigated on an oscillating pin on flat tester. A large difference in friction coefficient between Ti 3 SiC 2 /Ti 3 SiC 2 and Ti 3 SiC 2 /diamond pairs was observed. The friction coefficient of former is 1.16–1.43, but that of latter is below 0.1. The low friction coefficient of Ti 3 SiC 2 was attributed to the formation of a film on the Ti 3 SiC 2 tribosurface, which is similar to the behavior of graphite. In the other conditions, Ti 3 SiC 2 was not self-lubricated. Although Ti 3 SiC 2 has a layered structure and is anisotropy in chemical bonding, this work demonstrated that it is not intrinsically self-lubricated.
