Abstract: There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder. Next, a mixture is prepared by mixing the magnet powder and a binder made of long-chain hydrocarbon and/or of a polymer or a copolymer consisting of monomers having no oxygen atoms. Next, the mixture is formed into a sheet-like shape so as to obtain a green sheet. After that, the green sheet is held for a predetermined length of time at binder decomposition temperature in a non-oxidizing atmosphere so as to remove the binder by causing depolymerization reaction or the like to the binder, which turns into monomer. The green sheet from which the binder has been removed is sintered by raising temperature up to sintering temperature. Thereby a permanent magnet 1 is obtained.

Abstract: A sliding material has a sintered layer formed atop a backing plate. The sintered layer contains 5-15 mass % of Bi nonuniformly distributed in a Cu—Sn alloy matrix consisting essentially of 8-12 mass % of Sn and a remainder of Cu. The sliding material can be manufactured by nonuniformly mixing Cu—Sn alloy powder and Bi powder, dispersing the mixed powder on a backing plate, and sintering the mixed powder to form a sintered layer on the backing plate. The sliding material does not undergo seizing and does not have separation of the sintered layer from the backing plate even when used in severe conditions such as in hydraulic equipment or construction equipment.
