Abstract
A multilayered sliding member has a resin composition filled in pores of, and coated on the surface of, a porous sintered metal layer 2 formed on the surface of a metallic backing plate 1. The resin composition is formed by compounding a phosphate, a carbon black, a melt moldable fluororesin, and a PTFE serving as a principal component, and is preferably formed by further containing graphite and/or a low molecular weight PTFE.
Claims4
A multilayered sliding member comprising a resin composition filled in pores of, and coated on a surface of, a porous sintered metal layer formed on a surface of a metallic backing plate, said resin composition comprising
- 3 to 25% by weight of a phosphate which includes a magnesium metaphosphate,
- 0.3 to 3% by weight of a carbon black selected from acetylene black, oil furnace black, thermal black, channel black, or gas furnace black, which has a hollow structure, a porous structure, and a chain structure, whose DBP absorption is not less than 100 ml/100 g,
- 3 to 30% by weight of a melt moldable fluororesin selected from a tetrafluoroethylene-perfluoroalkylvinylether copolymer and a tetrafluoroethylene-hexafluoropropylene copolymer,
- 3 to 15% by weight of a low molecular weight polytetrafluoroethylene resin, and
- the balance of a polytetrafluoroethylene resin.
