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 (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 trinuclear Mo structure.

Abstract: [Technical Problem] An object is to provide a sliding system that allows the friction coefficient at a sliding part to be considerably reduced by means of a novel combination of a chromium nitride 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 that can be interposed between the sliding surfaces facing each other. At least one of the sliding surfaces comprises a coating surface of a specific chromium nitride film, and the lubricant oil contains an oil-soluble molybdenum compound comprising molybdenum dialkyldithiophosphate (Mo-DTP). When the chromium nitride film as a whole is 100 at % (referred simply to as “%”), the chromium nitride film comprises 40-65% of Cr and 35-55% of N and has a relative surface area of 15-85%.

Abstract: A sliding system includes a pair of sliding members having opposing sliding surfaces adapted to move relative to each other, and a lubricating oil interposed between the opposing sliding surfaces. Here, at least one of the sliding surfaces is a covered surface covered with a specific chromium nitride film. The lubricating oil contains an oil-soluble molybdenum compound formed of a molybdenum dialkyldithiocarbamate. In the chromium nitride film, when an amount of atoms constituting the entire chromium nitride film is set as 100 atom %, there is 32 atom % to 47 atom % of N, the balance is Cr, and a relative area which is an area ratio of the (111) plane with respect to the (200) plane obtained when the chromium nitride film is analyzed by X-ray diffraction is 20% to 30%.

Abstract: A low-friction sliding member is used under a wet condition employing a lubricant, and includes a substrate having a surface, and an amorphous hard carbon film formed on the surface of the substrate for contacting slidably with a mating member. The amorphous hard carbon film includes silicon in an amount of from 1 atomic % or more to 20 atomic % or less, hydrogen in an amount of from 20 atomic % or more to 50 atomic % or less, and the balance of carbon and inevitable impurities, when the entirety is taken as 100 atomic %, and exhibits a surface roughness Rzjis of 0.8 ?m or less. The low-friction sliding member exhibits reduced friction coefficients between itself and mating members, without relying on the adsorption and reaction of additives, included in lubricants, to the amorphous hard carbon films.
