    摘要： A sintered material for valve guides consists of, by mass %, 0.01 to 0.3 % of P, 1.3 to 3 % of C, 1 to 4 % of Cu, and the balance of Fe and inevitable impurities. The sintered material exhibits a metallic structure made of pores and a matrix. The matrix is a mixed structure of a pearlite phase, a ferrite phase, an iron-phosphorus-carbon compound phase, and a copper phase, and a part of the pores including graphite that is dispersed therein. The iron-phosphorus-carbon compound phase is dispersed at 3 to 25 % by area ratio, and the copper phase is dispersed at 0.5 to 3.5 % by area ratio, with respect to a cross section of the metallic structure, respectively.

    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 silicides, 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.
