| 摘 要： | 采用热压工艺制备了超高分子量聚乙烯(UHMWPE)/纳米氧化锆(ZrO2)髋臼复合材料,利用UMT试验机测试复合材料的硬度和剪切冲压性能,利用人工髋关节模拟磨损试验机考察了复合材料在小牛关节液润滑条件下的摩擦磨损性能.结果表明,填充ZrO2提高UHMWPE复合材料的表面硬度、断裂载荷和断裂功,降低其磨损率.ZrO2/UHMWPE复合材料的磨粒尺寸随着ZrO2含量的增加而升高.UHMWPE复合材料耐磨性能与其大变形行为相关,复合材料的磨损率与大变形行为参数断裂载荷和断裂功呈反比线性关系.

| 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... |
