COMPOSITE SLIDING MEMBER

摘要

There is disclosed a composite slide member which suppresses the exposure of a porous metal layer even when the amount of cutting from a surface of the slide member increases, thereby enhancing an anti-seizing property without adversely affecting a rear resistance. The composite slide member includes a back plate, and a slide layer including a porous metal layer with a porosity of 50% to 80% and a composite synthetic resin composition impregnated and coated in pores of the porous metal layer. The porous metal layer is joined to a surface of the back plate. The porous metal layer is formed by sintering metal powder without applying pressure thereto, and an apparent density of the metal powder is 20% to 40% of its theoretical density. The porous metal and the composite synthetic resin are dispersed on a sliding surface of the slide layer in a substantially mixed condition.
