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:
Forge lubrication processes are disclosed. A solid lubricant (38) sheet is placed between a workpiece (30) and a die (34; 36) in a forging apparatus. Force is applied to the workpiece (30) with the die (34; 36) to plastically deform the workpiece. The solid lubricant sheet (38) decreases the shear factor for the forging system and reduces the incidence of die-locking.
Abstract:
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Aufbringen von hexagonalem Bohrnitrid auf eine raue Oberfläche wobei das Bohrnitrid als temperaturbeständiges Schmiermittel der Oberfläche zur Verfügung stehen soll. Erfindungsgemäss wird Stift aus hexagonalem Bohrnitrit über die raue Oberfläche mit Druck gerieben so dass ein Abrieb von Bohrnitrid auf der Oberfläche haften bleibt.
