摘要： An oil-impregnated sintered sliding bearing formed of a porous iron-based sintered alloy with quenched structure and receiving a high surface pressure capable of reducing the number of finishing steps by cutting and grinding and providing a bearing performance equivalent to or higher than that of conventional bearings, wherein a plurality of ridge-and-groove lines having a height difference of 2 to 12.5 μm and extending in circumferential direction are axially arranged in parallel with each other by boring the bearing surface thereof to form a wavy surface in axial direction, and the portion thereof deeper by 10 to 60 μm from the outer layer of the bearing surface is formed dense to seal surface pores so as to reduce the pores opening to the outer surface to 1 to 10 percent by area, whereby the bearing can be used at a surface pressure of 6 kgf/mm2 (58.5 MPa) or higher and a sliding speed of 2 to 5 cm/s.

摘要： A sintered composite sliding part has an outer member made of an Fe-based wear resistant sintered member in which a hard phase is dispersed in a matrix at 15 to 70% by volume and an inner member made of a stainless ingot steel. The matrix is made of an Fe-based alloy including 11 to 35% by mass of Cr, and the hard phase is formed by precipitating and dispersing at least one selected from the group consisting of intermetallic compounds, metallic suicides, metallic carbides, metallic borides, and metallic nitrides in an alloy matrix made of at least one selected from the group consisting of Fe, Ni, Cr, and Co. The outer member is formed with a hole, the inner member is closely fitted into the hole, and the outer member and the inner member are diffusion bonded together.
