Low-friction lubrication assembly

Assemblage de lubrification a faible frottement

Reibungsarme schmierungsanordnung


[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.
