Abstract: High-strength brass 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.

Abstract: A sliding contact surface-forming material, and method of making the material are disclosed, the material having minimal swelling and excellent friction-proof and wear-proof characteristics when used in moist environments such as in water, and improved in the friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, particularly under oscillation conditions for testing journal. The material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, as each of the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.

Abstract: A sliding contact surface-forming material with improved friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, while keeping the low swelling, friction-proof, and wear-proof characteristics under moist atmosphere typically under water unchanged, wherein the sliding contact surface-forming material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein, the reinforcing base being composed of a woven fabric formed by using, respectively as the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyphenylene sulfide fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.
