Abstract:
[Technical Problem] An object is to provide a sliding system that can considerably reduce the friction by means of a novel combination of a sliding film and a lubricant oil. [Solution to Problem] The sliding system of the present invention comprises 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 comprises a coating surface of a crystalline Cr plating film. The lubricant oil contains an oil-soluble molybdenum compound that has a chemical structure of a Mo-trinuclear. 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 (P1 to P3) as obtained by X-ray diffraction falls within a predetermined range (P1≥0.015, P2≥0.02, P3≥0.03), and the lubrication oil which contains the Mo-trinuclear.

Claim (Index 1):
A sliding system comprising:\n 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, wherein the lubricant oil contains an oil-soluble molybdenum compound that has a chemical structure of a trinuclear of Mo, wherein at least one of the sliding surfaces comprises a coating surface of a crystalline chromium plating film, wherein a peak area I(hkl) of a crystal plane (hkl) of the chromium plating film as obtained by X-ray diffraction satisfies at least one of expressions below:\n P 1={ I (110)+ I (211)}/ I (222)\u22650.015; \n P 2={ I (110)+ I (310)}/ I (222)\u22650.02; and \n P 3={ I (110)+ I (211)+ I (310)}/ I (222)\u22650.03.
