Abstract

In this study, the effects of gamma irradiation on the tribological behaviors of high-density polyethylene (HDPE)-filled ultrahigh-molecular-weight polyethylene (UHMWPE) composites were investigated. The tribological changes were evaluated by friction and wear tests as well as scanning electron microscopic analysis of the worn surfaces. It was found that the irradiation induced the degradation of UHMWPE molecular chains and the interfacial cross-linking was formed. The addition of HDPE significantly increased the wear resistance of UHMWPE composites. Friction and wear tests indicated that HDPE improved the tribological properties of the materials before and after irradiation. HDPE and irradiation exhibited a good synergistic effect for improving the wear resistant and tribological properties of UHMWPE material.
