Abstract: Disclosed is a multi-layered plain bearing which comprises a steel back, an intermediate layer made of an aluminum alloy and an aluminum-base bearing alloy layer comprising one or more elements selected from the group consisting of Cu, Zn, Mg and Si. The aluminum-base bearing alloy layer is bonded to the steel back via the intermediate layer and subsequently subjected to a solid solution treatment at a temperature of not lower than 400null C. The adjacent region of the intermediate layer to the steel back consists of, by mass, 2% to 8% of Si, and the balance of Al and incidental impurities.

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.
