Abstract

Ultrahigh-molecular-weight polyethylene (UHMWPE) and nitrogen-doped graphene /Ultrahigh-molecular-weight polyethylene composite (NG/UHMWPE) samples were successfully fabricated through an optimized hot-pressing molding method. Friction and wear behavior of UHMWPE and NG/UHMWPE samples sliding against ZrO2 ceramic ball were investigated with a high-speed reciprocating friction tester. The mechanical property and wear volume of pure UHMWPE and NG/UHMWPE samples were characterized with micro-hardness tester and Micro-XAM 3D non-contact surface profiler. The worn morphology of pure UHMWPE and NG/UHMWPE samples were observed by scanning electron microscope (SEM). The results showed that, adding NG could not only improve the micro-hardness and wear resistance of UHMWPE and but also reduce the wear rate of UHMWPE significantly.
