摘要：There is provided a sliding part in which a surface coverage ratio of copper inthe sliding part increases. A bearing which is the sliding part is formed by filling the rawpowder into the filling portion of the forming mold, compacting the raw powder to form

a powder compact, which is sintered. A copper-based raw powder is composed of acopper-based flat raw powder whose diameter is smaller than that of an iron-based rawpowder and an aspect ratio larger than that of the iron-based raw powder, and a copper-based small-sized raw powder whose diameter is smaller than that of the copper-basedflat raw powder. The copper is allowed to segregate at the surface of the sliding part.The surface of the bearing is covered with the copper-based small-sized raw powder andthe copper-based flat raw powder, thereby the surface coverage ratio of copper can beincreased.
