Sliding member

Abstract

There is provided a sliding member that has sufficient wear resistance and good adhesion to a base formed of a sintered body. The sliding member includes a surface layer formed of a crosslinked fluoropolymer and a base that adheres closely to the surface layer. The base is a sintered body having a full density ratio in the range of 0.75 to 0.96 and is formed of a material having higher thermal conductivity than a fluoropolymer. The surface layer has a thickness in the range of 1 to 300 μm.

1 . A sliding member comprising:
 a surface layer formed of a crosslinked fluoropolymer; and   a base that adheres closely to the surface layer,   wherein the base is a sintered body having a full density ratio in the range of 0.75 to 0.96,   the base is formed of a material having higher thermal conductivity than a fluoropolymer, and the surface layer has a thickness in the range of 1 to 300 μm.   
     
     
         2 . The sliding member according to  claim 1 , wherein the base is an iron-based sintered body. 
     
     
         3 . The sliding member according to  claim 1 , wherein the surface layer has a thickness in the range of 10 to 100 μm. 
     
     
         4 . The sliding member according to  claim 1 , wherein the fluoropolymer is at least one selected from the group consisting of polytetrafluoroethylene, tetrafluoroethylene-hexafluoropropylene copolymers, and tetrafluoroethylene-perfluoroalkyl vinyl ether copolymers.
