摘要： There is provided a copper-based sliding alloy excellent in wear resistance and anti-seizure property. A phase of 2 to 30 wt. % lead is dispersed in the copper alloy. This lead phase contains 0.1 to 6 vol. % hard particles such as SiC, SiO2, Si3N4, Al2O3, TiC, WC and TiN having an average particle size of 5 to 25 &mgr;m. Because hard particles are included in the lead phase, wear resistance is excellent and anti-seizure property is improved. The lead phase, which is soft, serves as a cushion and the attack on a mating member by hard particles is reduced. Further, the falling-off of lead is minimized because the lead phase also includes the hard particles.

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 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： 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： In this sliding bearing, which is provided with a resin coating layer at the surface of a bearing alloy layer layered at a back metal layer, a PAI that degrades with difficulty at high temperatures is used as the main component as the resin binder of the resin coating layer, adjustment particles are included in the resin binder, and as a result, the compressive strength of the resin coating layer is increased, and indentations of the resin coating layer resulting from a shaft are prevented. Meanwhile, a plate solid lubricant is included in the resin binder, and thus sliding characteristics are improved. Also, delamination due to cracks is prevented by the effect of adjusting the orientation of the solid lubricant and the damming effect of the adjustment particles, and thus superior anti-seizure property is provided even in an engine that frequently repeats starting and stopping.
