Abstract: Provided is a method for producing a sliding member formed by impregnating a porous base member made of a bronze-based alloy with a resin material, the sliding member including a sliding surface where both the porous base member and the resin material are exposed, the method including: a step of preparing a back metal layer; a porous base member formation step of forming the porous base member by depositing particles of the bronze-based alloy on a surface of the back metal layer and sintering the particles; an impregnation step of impregnating the porous base member with the resin material; a deformation step of deforming an end edge of the back metal layer in a direction away from the sliding surface; and a cutting step of cutting the porous base member impregnated with the resin material to form the sliding surface.

Abstract: The present invention provides a sliding member which enables further reduction of friction and improvement of seizure resistance without deteriorating wear resistance of a sliding surface. The sliding member includes a porous metal base material, and a resin material with which the porous metal base material is impregnated. The sliding member includes an exposed sliding surface. The sliding surface includes a top surface made of the resin material, and a bottom surface made of the porous metal base material. A height from the bottom surface to the top surface is 10 to 30 μm, and the resin material includes fluorine resin.

Abstract: Disclosed is a resin sliding member, including: 0.5 to 25 vol % of calcium fluoride dispersed as particles; and a polyether ether ketone resin as a remainder. The calcium fluoride is crystalline, and a peak intensity of a (111) plane of the calcium fluoride exposed on a sliding surface is larger than a peak intensity of a (220) plane.
