Abstract
Nano-TiO(2)/UHMWPE composites were prepared by hot press procedure, and then radiated by gamma ray in dose of 120 kGy, 250 kGy and 500 kGy. The hardness of the composites was initially determined. Subsequently the wear against a CoCrMo alloy counterface were tested in a knee simulator under physiological saline lubrication. The morphologies of the worn surfaces were examined with optical microscope. The structure of the samples was determined by IR and XRD. The results showed that the wear rate of the composite UHMWPE decreased when filled with proper amount of nano-TiO(2) and with the radiation dose.Entities:
