Abstract
A multilayer sliding material for high-speed engine, comprising a steel back metal, a Cu or Cu-base alloy plating layer, a Cu-Pb bearing alloy layer, and an overlay, said steel back metal having 155 or more of Vickers hardness and 42 kgf/mm.sup.2 or more of 0.2% yield strength, a Cu-Pb bearing alloy layer containing 15-30 wt % of Pb and 0.5-2.0 wt % of Sn and having 0.25 cal/cm.s..degree. C. or more of thermal conductivity, 75 or more of Vickers hardness and 18 kgf/mm.sup.2 or more of tensile strength, said overlay of a lead base alloy containing 2-8 wt % of Sn and 3-11 wt % of In and having more than 250.degree. C. of melting start temperature. The material has a superior antiseizure property at high speed of engine. In particular, the rising of the melting start temperature of the metal of the overlay and the thermal conductivity of the bearing alloy provides a superior sliding property of plain bearing at high speed of engine.
