Low friction lubrication assembly

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.
