[0066]As raw materials, the Cu—Ni powder and the Ni—Cu powder; the Sn atomized powder with the grain size of 250-mesh; the Cu-8% P atomized powder with the grain size of 200-mesh; and the graphite powder were prepared. The atomized powders were obtained by the atomizing method, in which alloy melt having the intended composition was formed in a crucible in a high frequency melting furnace; and the alloy melt was quenched by spouting out the alloy melt from the ejection nozzle provided on the bottom part of the crucible into the inside of water body.
[0067]These raw material powders were blended to obtain the final component compositions shown in Table below. Then, 0.5% of zinc stearate was added, and the mixture was mixed for 20 minutes by a V-type mixer. Then, the mixture was subjected to press molding to produce a green compact. Next, the green compact was sintered at the predetermined temperature in the range of 960-1140° C. in the endothermic gas atmosphere, which was obtained by...

Abstract
A sintered sliding material with excellent corrosion resistance, heat resistance, and wear resistance is provided. The sintered sliding material has a composition made of: 36-86 mass % of Ni; 1-11 mass % of Sn; 0.05-1.0 mass % of P; 1-9 mass % of C; and the Cu balance including inevitable impurities. The sintered sliding material is made of a sintered material of a plurality of grains of alloy of Ni—Cu alloy or Cu—Ni alloy, the Ni—Cu alloy and the Cu—Ni alloy containing Sn, P, C, and Si; has a structure in which pores are dispersedly formed in grain boundaries of the plurality of the grains of alloy; and as inevitable impurities in a matrix constituted from the grains of alloy, a C content is 0.6 mass % or less and a Si content is 0.15 mass % or less.
