    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： 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： A sliding member has a sliding alloy layer, an intermediate layer of Ni or a Ni alloy formed on the sliding alloy layer, and a soft layer of Sn or a Sn alloy formed on the intermediate layer. A recess is formed on the sliding side surface of the sliding alloy layer. The intermediate layer is formed on the inner surface of the recess. The sliding member is subjected to a heat treatment, whereby there are formed intermetallic compounds in the soft layer, which extend protrudently from the intermediate layer.

    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.
