    摘要： A method of manufacturing a multilayer material including a back metal and a metal plate made from a metal differing from the back metal is disclosed. The method includes heating powder of the metal formed into the metal plate in a reducing atmosphere so that an oxide on a surface of the metal powder is deoxidized, and spreading the deoxidized metal powder onto the back metal and irradiating laser beam having an energy density of 10 to 100 kW/cm2 onto the metal powder spread on the back metal so that the metal powder is partially heated to be melted, while the laser beam is moved relative to the spread metal powder, and quenching the melted part of the metal powder at an underside of the back metal so that the melted part is rapidly solidified, whereupon the multilayer material has a dendritic structure in which the metal plate extends substantially vertically from a surface of the back metal, and the dendritic structure has a crystal grain size equal to or smaller than 0.02 mm at a cut surface thereof parallel to a surface of the back metal and/or a dendritic arm spacing equal to or smaller than 0.02 mm at a cut surface thereof vertical to the surface of the back metal.

    摘要： Disclosed is a composite sliding material having a steel plate and a sintered copper alloy layer which is bonded to the steel plate. The copper alloy contains, 1.5 to 15 mass % Sn, 1.5 to 15 mass % Bi, 1.5 to 20 volume % of a solid lubricant, and balance of Cu and incidental impurities. The volume ratio of Bi to the solid lubricant is in a range of 0.5 to 2.0. Bi and the solid lubricant improves the copper alloy in sintering property, since Bi melts when sintering because of a low melting point resulting in improved sintering property, and the solid lubricant ensures good anti-seizure property, and deterioration of mechanical strength is prevented by virtue of a phenomenon that the solid lubricant is entrained in Bi.
