Abstract
A sintered metal part has a magnesium metasilicate mineral, or a magnesium metasilicate mineral and a magnesium orthosilicate mineral, or at least one of a magnesium metasilicate mineral and a magnesium orthosilicate mineral and at least one of boron nitride and manganese sulfide dispersed throughout the metal matrix. An iron-based sintered sliding member is of a structure that free graphite and an intercrystalline inclusion have been dispersed throughout the metal matrix that consists essentially of, in weight ratio, 1.5 to 4% of carbon, 1 to 5% of copper, 0.1 to 2% of tin, 0.1 to 0.5% of phosphorus, 0.5 to 2% of an intercrystalline inclusion and the balance of Fe and has a mixed structure of a pearlite matrix with a steadite phase, the intercrystalline inclusion being a magnesium metasilicate mineral, or a magnesium metasilicate mineral and a magnesium orthosilicate mineral, or at least one of a magnesium metasilicate mineral and a magnesium orthosilicate mineral and at least one of boron nitride and manganese sulfide.
