Abstract: A copper-based sliding material produced by sintering, comprising at least two phases of copper and/or copper alloys which phases have hardness levels different form each other, and hard particles with an average particle size of 0.1 to 10 nullm which are dispersed in at least one phase with the exception of a softest phase in an amount of 0.1 to 10 vol.% of the whole copper-based sliding material, said sliding material satisfying (H2/H1)null1.2 in which H1 is the Vickers hardness of the softest phase and in which H2 is the Vickers hardness of a phase hardest in hardness including said hard particles.

Abstract: Bush 4 is fabricated by providing porous sintered metal layer 7 of copper on the surface side of back metal layer 5 of steel plate through copper plating layer 6 and coating the inside and the surface of porous sintered metal layer 7 with sliding material 8 by impregnation. Sliding material 8 comprises 1-25 vol. % of tetrafluoroethylene-perfluoroalkylvinyl ether copolymer resin, 1-25 vol. % of at least one member selected from the group consisting of oxybenzoylpolyester resin and polyimide resin and 0.1-10 vol. % of hard particles having a Mohs hardness of 4 or more and average particle sizes of 5 nullm or less such as Al2O3 and SiC, the balance being polytetrafluoroethylene resin (55 vol. % or more of the total siding material) as the main component. 0.5-25 vol. % of a solid lubricant such as graphite and MOS2 can be further contained in total together with the hard particles. The sliding material containing polytetrafluoroethylene resin as the main component has an improved fretting wear resistance particularly when used as a bearing material.
