Claim:
1. A low-friction lubrication assembly comprising: a first member relatively slidable against a second member, the first member having chemical affinity with an OH-group on its sliding surface; and one or more oxygen-containing compounds located on the sliding surface of the first member and being able to produce a tribofilm to be located on the sliding surface of the first member having the chemical affinity, through hydrogen bond interactions with the OH-group, wherein the first member includes a coating formed of a diamond-like carbon of ta-C type on its sliding surface, wherein the one or more oxygen-containing compounds include glycerol, wherein the second member has a chemical affinity with an OH-group on its sliding surface, and the tribofilm is able to be formed on the sliding surface of the second member through hydrogen bond interactions with the OH-group in response to a sliding motion of the first member against the second member, and wherein the second member includes a coating formed of a diamond-like carbon of the ta-C type on its sliding surface.
