Abstract: A sliding member includes a carbon transfer layer and can superiorly effectively decrease friction and reduce wear. A method produces the sliding member. The sliding member includes a substrate and a carbon transfer layer. The carbon transfer layer is disposed on the surface of the substrate and includes both sp2 bonded carbon and sp3 bonded carbon. The carbon transfer layer preferably has a ratio sp3/(sp2+sp3) of the sp3 bonded carbon to the totality of the sp2 bonded carbon and the sp3 bonded carbon of 0.1 or more.

Abstract: The present invention provides an initial running-in agent composition suitable for forming a low-friction surface (running-in surface) on a sliding member, such as a hard carbon film, in a system in which water is used as a lubricant. The initial running-in agent composition (10) according to an embodiment of the present invention contains water 11 as a lubricant base and nanodiamond particles (12). In the initial running-in agent composition (10), a content of the water (11) is preferably 99 mass % or greater, and a content of the nanodiamond particles (12) is preferably 1.0 mass % or less.

Abstract: 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.

Abstract: A water lubricant composition (10) of the present invention contains water (11) as a lubricating base material and ND particles (12), which are hydrogen-reduced nanodiamond particles. The content of the water (11) in the water lubricant composition (10) is, for example, 90% by mass or more. The content of the ND particles (12) in the water lubricant composition (10) is, for example, 0.1% by mass or less. The water lubricant composition (10) is suitable for achieving low friction in water lubrication. A water lubricating system of the present invention includes the water lubricant composition (10) which is being used for the lubrication of a SiC member and/or a SiO2 member.

Abstract: Provided is a cast iron material from which excellent friction characteristics can be obtained. Provided is the cast iron material containing C and Fe as a composition, and further containing Cr as the composition in 1.0 to 3.5% in terms of mass %. The cast iron material is used in a sliding component sliding under an environment of lubricating oil to which an additive containing Mo as a constituent element, such as MoDTC, is added. Cr contained in the cast iron material promotes a decomposition reaction of the additive containing Mo added to the lubricating oil to form a film of molybdenum disulfide, the film having low friction. Thus, the fiction can be reduced.

Abstract: In a sliding device, a first base member and a second base member are slid relative to each other. A hard carbon film is disposed on at least one of a first surface of the first base member and a second surface of the second base member opposed to the first surface of the first base member. Further, an intermediate layer is disposed between the hard carbon film and the one of the first surface of the first base member and the second surface of the second base member. The intermediate layer is made of a compound containing silicon and oxygen.
