    摘要： A Cu-based wear-resistant alloy of a sliding material consists essentially of, by weight, 10-35% Zn, 2-20% Pb, 1-10% Ni, 0.1-1% B and, as required, 0.5-10% of Sn. The alloy can be used under severe conditions of use at elevated speed and temperature with reduced risk of seizure and corrosion. The alloy can be produced by mixing Pb powder and Ni--B alloy powder with Cu--Zn powder or Cu--Zn--Sn alloy powder, or mixing Ni--B alloy powder with Cu--Zn--Pb alloy powder or Cu--Zn--Sn--Pb alloy powder. The alloy can be compacted and sintered to form a sliding member or a composite sliding member is obtained by sintering and integrating the alloy on a steel backing plate optionally having a surface plated with copper.

    摘要： A Cu-Pb system composite bearing has three layers including a backing metal, a bearing alloy layer formed on the backing metal, and an overlay formed on the bearing alloy layer. The Cu-Pb bearing alloy contains 2 to 10% Ni and 0.05 to 1.0% B. An example of the composition of the Cu-Pb system bearing alloy consists of 0.5 to 8% Sn, 15 to 30% Pb, 0.2% or less P, 2 to 10% Ni, 0.05 to 1.0% B and the balance of Cu and unavoidable impurities. The Cu-Pb bearing alloy must have a hardness over HV80. Ni and B contained in the bearing alloy decrease the affinity of the Cu-Pb bearing alloy for tin in the overlay of a tin-containing lead alloy. The corrosion resistance of the bearing is improved by plating the both surfaces of the composite bearing with Sn, Pb or an alloy thereof.

    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 sliding bearing has a back metal made of a copper alloy which has a high followability with respect to deformation of a light alloy housing, and with this construction, the sliding bearing is excellent in fretting resistance and migration resistance. The multi-layer sliding bearing for a light alloy housing includes an aluminum alloy bearing layer, and a back metal layer, the back metal layer being made of a copper alloy which has a thermal expansion coefficient of not less than 15.times.10.sup.-6 /.degree.C., a 0.2% yield strength of not less than 295 N/mm.sup.2 and a heat transfer coefficient of not less than 0.40 Cal/cm.cndot.sec.cndot..degree.C. A Pb-alloy overlay layer can be formed on the bearing layer. A bonding layer can be formed between the bearing layer and the back metal layer. A flash plating layer can be formed on an entire surface of the bearing. When a large interference is not obtained, or under sever conditions as when the temperatures of the bearing and the lubricating oil rise in a high-speed range of the internal combustion engine or as when the inertia force of the housing increases, an excellent bearing performance is achieved by the sliding bearing of the present invention.
