    摘要: [Object] A low friction assembly is desired.[Solving Means] 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.

    摘要: [Summary][Object] To provide a low-friction sliding mechanism capable of exhibiting an extremely excellent ultra-low friction characteristics at a sliding face existing in a variety of uses.[Solving means] A low-friction sliding mechanism is constituted by disposing a lubricant containing glycerol, at a sliding face formed between sliding members which have respectively hard carbon thin films. A low-friction sliding mechanism is constituted by disposing a lubricant containing hydroxyl group, at a sliding face formed between sliding members which have respectively hard carbon thin films, wherein a friction coefficient of smaller than 0.02 is exhibited in a sliding contacting condition under a boundary lubrication which exhibits a friction coefficient of 0.1 to 0.14 at a sliding face between a steel and a steel in presence of an engine oil. Each hard carbon thin film is formed of a-C or ta-C. Each hard carbon thin film has a hardness of 1500 to 5000 Hv in micro-Vickers hardness under a load of 10 g. Each hard carbon thin film has a film thickness of 0.3 to 2.0 μm. The lubricant containing hydroxyl group is one of alcohols, and is glycerol.
