A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each lubricant additive molecule includes a surface active group attractable to a target surface, and a carbon containing component connected to the surface active group, for providing a carbon source to form a carbon film on the target surface. A method for in situ forming of a carbon film using the lubricant composition, includes adding the lubricant composition into a target machine such that the lubricant composition is in contact with a target surface of the target machine, and operating the target machine to cause a temperature and a pressure at the target surface so that the carbon containing component is unraveled thereon to form a carbon film on the target surface during the operation.

A sliding member having a sliding surface that is at least partially formed of a surface of a lubricating member is provided. The sliding member includes: a base body as a sintered body of a compact containing metal powder, the base body being integrated with the lubricating member; and the lubricating member as an injection molded product of a resin composition containing a polyarylene sulfide-based resin and a carbon material.

Methods and systems in which a shapable mass, which is processed according to the method or in the system, has a lubricant applied thereto. As it is processed in the system, the shapable mass having the lubricant applied thereto is used to transfer lubricant to a part or parts of the system.

A sliding member includes: a base material; a solid lubricant layer arranged on a surface of the base material; a defect layer having a material defect, disposed in the solid lubricant layer, and being changeable into an ultra low friction layer by mechanical stress more easily than changing from the solid lubricant layer to the ultra low friction layer; and a ultra low friction layer covering a surface of the defect layer.

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%.
