摘要： Disclosed is a copper alloy sliding material comprising 0.5 to 15 mass % Sn and 0.1 to 10 vol % of hard particles consisting of one or more selected from WC, W2C and Mo2C. The hard particles have preferably an average particle size of 0.1 to 10 &mgr;m, whereby they are dispersed in the copper alloy matrix so as to make the sliding-contact surface uneven, from which the hard particles protrude partially. The sliding material comprises an amount or a total amount of not more than 40 mass % of one or more selected from Ni, Ag, Fe, Al, Zn, Mn, Co, Si and P, an amount or a total amount of not more than 10 mass % of Bi and/or Pb, and/or an amount or a total amount of not more than 10 vol % of a solid lubricant comprising BN, graphite, MoS2 and/or WS2.

摘要： A copper alloy sliding material which can bring about superior resistance to fatigue as well as good anti-seizure property without containing any Pb. The copper alloy sliding material is made to have the structure in which both of the hard copper alloy phase and the soft copper alloy phase coexist in a mixture state. On the surface of the sliding material, the soft copper alloy phase comes to have a shape more concave than that of the hard copper alloy phase when receiving a load or when being in a sliding wear relation, in which concave portions is retained lubricant with the result that the anti-seizure property is enhanced. Further, since the soft phase and the hard phase are made of the same copper alloy, the wettability thereof becomes good, and Ni and etc. contained in the hard copper alloy phase are diffused into the soft copper alloy phase, so that the hardness of the boundary portion defined between the phases come to be gradually varied. Thus, because of the unclear boundary, the load received in the hard phase comes to be spread in a wide range without being concentrated at the boundary, so that the fatigue strength is enhanced.
摘要翻译：一种铜合金滑动材料，可以带来优异的抗疲劳性以及良好的抗咬合性能，不含任何Pb。使铜合金滑动材料具有混合状态下硬铜合金相和软铜合金相共存的结构。在滑动材料的表面上，软铜合金相的形状比硬铜合金相的形状比承受载荷或滑动磨损关系时更凹形，其中凹部保持有润滑剂导致抗发作性能得到提高。此外，由于软相和硬相由相同的铜合金制成，所以其润湿性良好，硬铜合金相中所含的Ni等扩散到软铜合金相中，使得硬度两相之间界定的边界部分逐渐变化。因此，由于边界不清楚，硬相中承受的载荷在宽范围内扩散而不会集中在边界处，从而提高了疲劳强度。

摘要： Disclosed is a copper alloy sliding material having a metal structure wherein intermetallic compounds exist adjacently to Pb-phase islands and/or Bi-phase islands. Because intermetallic compounds exist between the matrix and the Pb phase and/or the Bi phase, the material can have improved anti-seizure property, since, under load or due to wear, the surface of the material has recessions at the soft Pb and/or Bi phase and the matrix with respect to the intermetallic compounds.

摘要： There is disclosed a sliding member which slidably contacts an counterpart member with friction and in which a friction force is varied without changing a contact pressure. A sliding member 11 is formed by covering a steel plate with sliding materials 13a to 13e different in friction coefficient. In this case, when a sliding direction of the counterpart member 14 is set to directions of arrows A and B, a sliding material 13a of a low friction coefficient is disposed in the middle, and the sliding materials 13b to 13e are arranged so that the friction coefficient gradually increases toward both terminal sides in the directions of arrows A and B of the sliding material 13a. According to the sliding member 11, the friction force increases as the counterpart member 14 moves in the directions of arrows A and B from the middle.

摘要： Disclosed is a composite sliding material having a steel plate and a sintered copper alloy layer which is bonded to the steel plate. The copper alloy contains, 1.5 to 15 mass % Sn, 1.5 to 15 mass % Bi, 1.5 to 20 volume % of a solid lubricant, and balance of Cu and incidental impurities. The volume ratio of Bi to the solid lubricant is in a range of 0.5 to 2.0. Bi and the solid lubricant improves the copper alloy in sintering property, since Bi melts when sintering because of a low melting point resulting in improved sintering property, and the solid lubricant ensures good anti-seizure property, and deterioration of mechanical strength is prevented by virtue of a phenomenon that the solid lubricant is entrained in Bi.
