Abrégé

A low friction assembly is desired. The present invention relates to a new 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, provided on the sliding surface of the first member and being able to produce a tribofilm attached to the sliding surface of the first member through hydrogen bond interactions. Preferably the second member comprises a similar OH-terminated sliding surface wherein an oxygen containing compound (lubricant)-supported interface between the first and second sliding surfaces results in a H- and/or OH-terminated interface developing repulsive forces thereinbetween.

Abrégé

The invention provides a low-friction sliding mechanism, a low-friction agent composition, a friction reduction method, a manual transmission and a final reduction gear unit that can exert very excellent low friction characteristics to sliding surfaces present under various applications, and, in particular, that have more excellent low friction characteristics than that of a combination of an existing steel material and an organic Mo compound. The low-friction sliding mechanism has an oxygen-containing organic compound or an aliphatic amine compound interposed between sliding surfaces that a DLC coated sliding member and a sliding member form. The low-friction agent composition contains an oxygen-containing organic compound or an aliphatic amine compound. The friction reduction method includes supplying the low-friction agent composition between sliding surfaces that a DLC coated sliding member and a sliding member form. The manual transmission includes, as at least one of sliding members, a DLC coated sliding section. The final reduction gear unit includes, as at least one of sliding members, a DLC coated sliding section.
