Biotribological Behavior of Ultra High Molecular Weight Polyethylene Composites Filled with Nano -ZrO2
|
Abstract:
The artificial joint material of UHMWPE composite filled with nano-ZrO2 in different contests was prepared with a pressing formation method.Hardness and shear punch behavior of ZrO2/UHMWPE composites were measured with UMT tribo-tester.Biotribological behavior of the composites was investigated with a hip joint simulator under lubrication of calf bovine synovial.The experimental results indicated that nano-ZrO2 filler increased the hardness,frature load and fracture work of composites,and reduced the wear r...
