Abstract
A sliding system includes a pair of sliding members having sliding surfaces that can relatively move while facing each other and a lubricant oil interposed between the sliding surfaces facing each other. At least one of the sliding surfaces includes a coating surface of a crystalline Cr plating film. The lubricant oil contains an oil-soluble molybdenum compound comprising a trinuclear Mo structure. In particular, considerably low friction properties can be developed by a combination of the Cr plating film, in which at least one of three types of peak area intensity ratios (Pto P) as obtained by X-ray diffraction falls within a predetermined range (P≥0.015, P≥0.02, P≥0.03), and the lubrication oil which contains the trinuclear Mo structure.
