摘　　要：利用MM 200型摩擦磨损试验机研究了不同质量含量的纳米CuO填充UHMWPE基复合材料在干摩擦条件下与45#钢对磨时的摩擦学性能。并利用扫描电子显微镜(SEM)观察分析磨损表面形貌及磨损机理。结果表明,纳米CuO/UHMWPE复合材料的摩擦性能与纯UHMWPE相比大部分均有提高,但耐磨性明显优于后者,纳米CuO在复合材料中的最佳含量在15%～17%左右。The friction and wear properties of nanometer CuO filled UHMWPE composite blocks with different filler proportions in sliding against 45 steel ring under dry friction conditions were studied.The worn surfaces were then investigated by a scanning electron microscope(SEM).The results showed that filling UHMWPE with nanometer CuO could greatly reduce the wear of UHMWPE composites and the best antiwear property was obtained with containing 15%～17% nanometer CuO.
