Abstract: Provided are: a solid lubricant having a low friction coefficient and excellent abrasion resistance; and a sliding member having this solid lubricant embedded therein. The solid lubricant (4) has a sea-island structure, comprising: a sea phase as a continuous phase, containing a hydrocarbon-based wax and a polyethylene resin; and an island phase as a dispersion phase, containing a low-molecular weight tetrafluoroethylene resin, a higher fatty acid salt, a phosphate of basic nitrogen-containing compound, and zinc stannate. A high-molecular weight tetrafluoroethylene resin is contained in this continuous-phase sea phase in a fibrous and mesh state. The hydrocarbon-based wax content is 30-60 vol %, the polyethylene resin content is 3-10 vol %, the low-molecular weight tetrafluoroethylene resin content is 10-30% vol %, the higher fatty acid salt content is 20-40% vol %, the basic nitrogen-containing compound phosphate content is 0.5-5 vol %, the zinc stannate content is 0.

Abstract: High-strength brass alloy having superior wear maintains single-structure ? phase and Fe—Cr—Si-based intermetallic compounds dispersed in the ? 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 ? phase and Fe—Cr—Si-based intermetallic compounds are dispersed in the ? phase. The high-strength brass alloy for sliding member has the structure in which the matrix shows single-structure of ? phase and hard Fe—Cr—Si-based intermetallic compounds are dispersed in the ? phase. Thus the hardness is increased and wear resistance is improved.

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).
