摘  要:
Ultra high molecular weight polyethylene (UHMW PE) is a kind of engineering plastic with many outstanding physical and mechanical performances. It may substitute for metal materials and widely applied in mechanical fields of centrifugal pump, bearing and so on. The effects of molecular weight, time, rate, load and stuffing on the friction and wear characteristics of UHMW PE were studied by a MPV200 model of friction and wear tester and a caustic wear tester. At the same time, the worn surface was observed by a scanning electron microscope. The wear mechanism and characteristic of the UHMW PE engineering plastic were systemically analyzed. The results reveal that the wear mechanism of the UHMW PE plastic alloy was furrow and rupturing of subsurface stratum. The results from this paper are of important value for optimization of structure and property of materials.
