It’s important to research on the biotribology of UHMWPE composites for developing the new joint implanted materials and the life of the joint replacements. In this research, UHMWPE-NC composites were prepared using the pressing formation method. The nano-hardness and elastic modulus evaluations of all of UHMWPE-NC composites were obtained by nanoindentation tests (Hysitron, Co.,) with the corresponding load-displacement curves confirming the characteristic properties of these materials. A ball-on disc wear test was run on the Universal Micro-Tribometer (UMT) to investigate the friction and wear behaviors of Si3 N4 ceramic cross-sliding against UHMWPE-NC composites in artificial body fluids lubrication.
