Abstract:
PROBLEM TO BE SOLVED: To provide a plain bearing for an internal combustion engine assuring a low friction coefficient and excellent non-seizure characteristics while maintaining fatigue resistance. SOLUTION: The plain bearing for the internal combustion engine comprises a slide layer 6 including a lubricant outer layer 5 in which a solid lubricant is contained. The lubricant outer layer 5 contains an element which is contained in the solid lubricant at a maximum concentration of not less than 5 mass% in the lubricant outer layer, at least a particle 4 of the solid lubricant structured by gathering a plurality of primary particles exists on a surface of the lubricant outer layer 5, and the solid lubricant gathered particle exists wherein a long side of the solid lubricant particle 4 is equal to or longer than 20 μm and shorter than 100 μm in a surface visual field of the lubricant outer layer 5.

Abstract:
A resin composition which exhibits good sealability while keeping creep deformation to a minimum when brought into sliding contact with a mating member at a high contact pressure of over 10 MPa, and which will not damage a mating member made from an aluminum alloy while sliding in contact with lubricating oil. The resin composition is a pressure-resistant, sliding tetrafluoroethylene resin composition containing 100 parts by volume of a modified tetrafluoroethylene resin in the form of a copolymer of tetrafluoroethylene and partially modified tetrafluoroethylene, 5-40 parts by volume of carbon fiber, and 2-30 parts by volume of calcium sulfate whiskers having a Mohs hardness of 4 or less, and having, at 100° C., a maximum deformation rate in 24 hours, of 15% or less. A seal device to be brought into slide contact with an aluminum metal is molded from such a pressure-resistant, sliding tetrafluoroethylene resin composition.
Abstract:
Waterborne lubricants comprising: (A) water-soluble inorganic salt; (B) homogeneously dispersed solid lubricant; (C) at least one homogeneously emulsified substance selected from mineral oils, animal and plant oils and fats, and synthetic oils; (D) surfactant; and (E) water, in which the weight ratio (B)/(A) is from 0.05:1 to 2:1 and the weight ratio {C/(A + B)} is from 0.05:1 to 1:1, provide a one-step, highly lubricating waterborne lubricant for use in the cold plastic working of metals. This waterborne lubricant can replace the conversion coating treatment (phosphate, oxalate, etc.) + reactive soap treatment combined lubrication system now in general use and is free of the environmental issues associated with the combined lubrication system, provides for facile coating removal, and is not subject to the decline in seizure resistance caused by nonuniform add-on when large numbers of workpieces are treated together by immersion.
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricating grease which adds little load to the environment if it is eluted into water. SOLUTION: The lubricating grease contains a base oil being polyoxypropylene glyceryl ether and a density controlling powder. The grease contains a thickener which is lithium soap but may be something else. Because the grease contains the base oil being polyoxypropylene glyceryl ether, it sparingly dispersed in water and reduces the formation of an oil film. The contained density controlling powder can control the floating and sinking of the grease to or in water and facilitates its recovery or other treatments. COPYRIGHT: (C)2004,JPO
Abstract:
The coating comprises a solid matrix adhering to the substrate in which are dispersed particles of solid lubricants from at least two classes which are selected to exert a synergistic effect between themselves and with the constituents of the matrix. Protection against corrosion and against galling of the threadings of threaded elements used in h drocarbon wells.
Abstract:
According to the invention there is provided a liquid friction control composition characterized as either having a high and positive friction characteristic or a low and neutral friction characteristic, comprising a retentivity agent. The liquid friction control composition may also comprise other components such as a solid lubricant, a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems.
