The invention relates to an elementary
powder sintered iron-
copper-based oil-containing anti-friction material and a manufacturing method thereof. The anti-friction material is composed of the following raw materials in percentage by
mass: 67%-71% of Fe, 28.4%-32.4% of Cu, 0.6% of Sn, and 0.7% of
zinc stearate; the oil percentage in volume of the material is 17%-22%. The oil-containing anti-friction material adopts elementary iron and
copper mixed
powder, wherein
iron powder is reduced
iron powder,
copper powder is mixed powder of electrolytic copper powder and atomized copper powder. The
iron powder and the copper powder of the elementary iron and copper mixed powder are mixed uniformly, and thus the phenomenon of segregation due to different densities of iron powder and copper powder is avoided. The uniformly mixed powder is subjected to process operations of pressing,
sintering, finishing, oil impregnation and the like to obtain the
powder metallurgy iron-copper-based oil-containing anti-friction material with excellent properties. The oil-containing anti-friction material has the advantages that the raw materials adopt elementary mixed powder and are low in price; after
sintering, the material is uniform in
microstructure, free of segregation, and stable in property; the copper content is high, and the
wear resistance is good; the material contains no lead, and meets environmental requirements; when the
sintering temperature is 1040 DEG C, the
wear resistance of the material even exceeds that of an iron-copper-based oil-containing anti-friction material prepared from pre-
alloy powder.
