| Abstract: | Particles retaining at the friction interface of conventional micro-particles filled PTFE may cause wear of the materials. The modified nano-particles filled PTFE, however, can improve such state, which arouses great interests of the researchers in the field. This paper presents the research situations of nano-particles filled PTFE. The friction reduction and anti-wear mechanism of nano-particles filled PTFE are discussed, with the conclusion that the adhesion strength of nano-particles anti the PTFE matrix at the interface are critically important to anti-wear of the composites. Based on the mechanisms of interface treatment of composites and the surface adhesion of PTFE, new methods of interface modification of nano-particles filled PTFE are presented. |
