LOW-FRICTION LUBRICATION ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a low-friction lubrication assembly showing improved sliding characteristics than a low-friction assembly of a conventional technology.

SOLUTION: The new excellent friction lubrication assembly includes a first member which is slidable relatively against a second member. The first member is a member which has chemical affinity with OH groups on its sliding surface. The first member includes one or a plurality of oxygen-containing compounds which are located on the sliding surface of the fist member and can form a tribofilm deposited on the sliding surface of the first member typically through hydrogen bond interaction. The second member has a similar OH-terminated sliding surface. Preferably, the interface supported by the oxygen-containing compound (lubricating agent) between the first and second sliding surfaces has an H- and/or OH-terminated interface, and repulsion is provided between these interfaces.
