Abstract: Provided are a multilayer sliding member capable of being efficiently manufactured at a low cost and having little dimensional change with respect to being used with high loads, and manufacturing technology for same. A binder (5) is applied to a surface (21) of a metal plate (2) that is the backing material. Furthermore, a prepreg (3), formed by drying a woven cloth after the same is impregnated with a phenolic resin, is layered thereupon, and a sliding layer that was forcibly plastically deformed is formed on the surface (21) of the metal plate (2) by thermal curing the layered body while applying pressure with a force greater than the maximum anticipated load during use. A metal powder sintered layer (4) may also be formed on the surface (21) of the metal plate (2). Here, a thermosetting resin (such as a low-viscosity phenolic resin, or an epoxy resin) having a low viscosity and a high affinity with the phenolic resin used in the prepreg (3) is used in the binder (5).

Abstract: High-strength brass alloy having superior wear maintains single-structure β phase and Fe—Cr—Si-based intermetallic compounds dispersed in the β phase. A high-strength brass alloy for sliding member comprises Zn from 17% to 28%, Al from 3% to 10%, Fe from 1% to 4%, Cr from 0.1% to 4%, Si from 0.5% to 3%, mass ratio, and the remnant including Cu and inevitable impurities. The high-strength brass alloy has structure in which the matrix shows single-phase structure of β phase and Fe—Cr—Si-based intermetallic compounds are dispersed in the β phase. The high-strength brass alloy for sliding member has the structure in which the matrix shows single-structure of β phase and hard Fe—Cr—Si-based intermetallic compounds are dispersed in the β phase. Thus the hardness is increased and wear resistance is improved.
