The antifriction composite coatings are composed of epoxy resin, PTFE and graphite and dispersant FC2400. The antiwear p roperties and surface appearance for these composite coatings were studied by X2ray diffraction, SEM. The results show that the composite coatings have a good antifriction p roperty and thermal stability.
