摘要： A sliding part in which a surface coverage ratio of copper in the sliding part increases. A bearing which is the sliding part is formed by filling the raw powder into the filling 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 of a 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, and a copper-based small-sized raw powder having the average diameter is smaller than that of the copper-based flat raw powder. The copper segregates at the surface of the sliding part. In the bearing in which the copper-based flat powder segregates at the surface, the surface is covered with the copper-based small-sized raw powder that has emerged on the surface, as well as the copper-based flat raw powder, thereby it is possible to increase the surface coverage ratio of copper. Furthermore, containing calcium fluoride improves the seizure resistance.

摘要： A bearing is manufactured by filling iron-based material powder and copper-based material powder in a filling portion of a mold, compacting those material powder so as to for a green compact, and then sintering the green compact. The copper-based material powder contains flat powder particles, the flat powder particles having a large aspect ratio than particles of the iron-based material powder. The coppers-based powder particles segregate on a sliding surface by vibration. The sliding surface of a bearing is covered with copper, and a ratio of iron increases from the sliding surface toward the inside. Since a rotation shaft slides on the sliding surface covered with copper, a frictional coefficient between the rotation shaft and the sliding surface is reduced, thus enabling a smooth rotation thereof. Simultaneously the usage of iron imparts predetermined strength and durability.

摘要： There is provided an oil-impregnated sintered bearing which enable to prevent oil leakage from an outer peripheral surface of an bearing body. The oil-impregnated sintered bearing includes a bearing body which is made of a porous sintered alloy containing vacancies and has a bearing hole in which a rotary shaft can be inserted, wherein the vacancies opened on an outer peripheral surface of the bearing body are crushed. The vacancies may be crushed in the state of a green compact, or in the state of a sintered alloy after sintering the green compact. Consequently, the oil leakage from the outer peripheral surface of the bearing can be prevented, and oil pressure in the bearing hole can be preserved.
