摘要：

The effect of CuS, CuO, CaF2, and ZnF2 fillers in particulate sizes of 200-350 mesh on the friction and wear behavior of polyphenylene sulfide (PPS) was investigated. The filler proportion studied was 35 vol.%. The specimens which were prepared by compression molding were tested for friction and wear in a pin-on-disc configuration using hardened tool steel disc as the counterface. The morphologies of the worn surfaces and the transfer films were studied by scanning electron microscopy and the transfer films were analyzed by energy dispersive spectroscopy. The improvement in wear resistance with CuS was considerable and with CuO marginal, while the wear resistance decreased with CaF2 and ZnF2. The coefficient of friction increased significantly with CuO and decreased with CaF2 and was not significantly affected by the other fillers. The changes in the friction and wear behaviors were analyzed in terms of the morphology and the composition of transfer films. (C) 1998 Elsevier Science S.A.
