Abstract: Seizure resistance and wear resistance of Cu—Bi—In copper-alloy sliding material are enhanced by forming a soft phase of as pure as possible Bi. Mixed powder of Cu—In cuprous alloy powder and Cu—Bi containing Cu-based alloy powder is used. A sintering condition is set such that Bi moves outside particles of said Cu—Bi containing Cu-based powder and forms a Bi grain-boundary phase free of In, and In diffuses from said Cu—In containing Cu-based powder to said Cu—Bi containing Cu-based powder.

The invention relates to a sliding material composition for use in a sliding member whose counterpart sliding member is configured of rubber, the sliding material composition comprising a binder resin, 5 to 25 vol % of an N?-monoacyl basic amino acid, 5 to 25 vol % of molybdenum disulfide, and 5 to 20 vol % of polytetrafluoroethylene.

Abstract: The copper alloy (lining) prevails in an overwhelmingly large amount in a plain-bearing layer structure. Cu of the plain bearing copper-alloy diffuses into the Sn-based overlay diffuses into the Sn-based overlay and detrimentally impairs the performance of the overlay. The present invention takes a measure against this problem. An Sn-based overlay having a thickness of 3 to 19 ?m is deposited by electro-plating without an intermediate layer for diffusion prevention on a plain-bearing layer, which contains Sn and Ni in a total amount of more than 4 mass % to 20 mass % (the minimum amount of Sn is 4 mass %) and has a hardness of Hv 150 or less.

Abstract: [Task] The adhesion resistance of Cu—Bi based or Cu—Sn—Bi based alloy is lower than that of Cu—Sn—Pb based alloy, and also since conformability of the former alloy is low. Therefore, when Bi of the former alloy adheres onto an opposite shaft, seizure of the former alloy is likely to occur as compared with the case of the latter Cu—Sn—Pb based alloy. In is alloyed in the Bi phase of the Cu—Sn—Bi—In based copper alloy. The In-alloyed Bi phase has a considerably low melting point and therefore the sliding properties deteriorate. [Means for Solving] A Pb-free copper-based sintered sliding material has a composition that 0.5 to 15.0 mass % Bi and 0.3 to 15.0 mass % In, with the balance being Cu and inevitable impurities. With regard to the existence of Cu, Bi, and In, the material consists of a Cu matrix containing In, a Bi phase, and an In concentrated region in said Cu matrix at a boundary of said Bi phase.
