摘要： A bearing material is produced by forming a Cu-Pb-system or Pb-bronze-system bearing alloy layer on a steel plate optionally plated with Cu, and forming a Pb alloy overlay containing Zn on the bearing alloy layer so as to enhance corrosion resistance and conformability of the bearing alloy layer. A Cu-Zn alloy layer of 0.5 to 10 .mu.m is present between the Cu matrix of the bearing alloy layer and the overlay. The Cu-Zn alloy layer prevents Sn and In in the overlay from diffusing into the Cu matrix of the bearing alloy layer. The multi-layered slide bearing material can be manufactured by forming the bearing alloy lining layer on the steel plate optionally plated with Cu so as to obtain a bimetal plate, rolling the bimetal plate and a lead alloy plate for the overlay containing Zn to bond the plates in accumulative reduction of 8 to 48%, and thereafter subjecting the plates to heat treatment at 170.degree. to 250.degree. C.

摘要： A multi-layer bearing consists of a backing steel plate, a layer of Cu--Pb bearing alloy comprising, by weight, 1 to 20% of Ni and containing Pb-phase grains dispersed in the matrix, and an overlay of Pb alloy containing In. In in the overlay is diffused into the Pb-phase grains in the bearing alloy layer and forms a diffusion layer of high corrosion resistance in which In coexists with the Pb-phase grains, in an area of 30 to 200 .mu.m from the interface to the overlay. Even if the overlay is worn and the Cu--Pb bearing alloy layer is exposed, high corrosion resistance will be maintained.

摘要： A copper-alloy slide bearing for a low-rigidity housing having a three-layer structure of a steel back-metal, a copper-alloy layer and an overlay, the back metal containing 0.03 to 0.26% by weight of carbon. During the production of the slide bearing, a bimetal is prepared in such a manner that a back-metal portion is rolled at a total rolling reduction of 10 to 35%, and the resultant bimetal is heat-treated at a relatively low temperature, so that the slide bearing includes a back metal having a 0.01% elastic limit of not less than 300 N/mm.sup.2. When the copper-alloy slide bearing is used in a low-rigidity housing of an internal combustion engine, the slide bearing is capable of more excellently following the deformation of the housing, as well as capable of providing more excellent intimate contact and more excellent fretting resistance, than a conventional multi-layer slide bearing.

摘要： A multi-layer sliding bearing having an excellent anti-fretting property, comprises a back steel layer, and a bearing alloy layer formed on the back steel layer. A film of phosphate having a thickness of 0.1-15 .mu.m is formed on a back surface of the back steel layer, thereby enhancing the anti-fretting property of the bearing. The provision of the phosphate film well compatible with a mating material overcomes damage to the bearing due to fretting in a high-speed range. Therefore, the bearing can fully exhibit a bearing performance even under severe conditions of use in a high-speed, high-temperature and high-load range as typically experienced in a high-performance engine.
