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

compact, and sintering the powder compact. A copper-based raw powder is composed ofa copper-based flat raw powder having an average diameter smaller than that of an iron-based raw powder and an aspect ratio larger than that of the iron-based raw powder, anda copper-based small-sized raw powder having the average diameter is smaller than thatof the copper-based flat raw powder. The copper segregates at the surface of the slidingpart. In the bearing in which the copper-based flat powder segregates at the surface, thesurface is covered with the copper-based small-sized raw powder that has emerged onthe surface, as well as the copper-based flat raw powder, thereby it is possible toincrease the surface coverage ratio of copper. Furthermore, containing calcium fluorideimproves the seizure resistance.
