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 tribological properties of nano-CuO-filled UHMWPE matrix composites with different mass contents on 45 # steel under dry friction conditions were studied by MM 200 friction and wear tester. The wear surface morphology and wear mechanism were analyzed by scanning electron microscope (SEM). The results show that most of the tribological properties of nano-CuO / UHMWPE composites increase compared with that of pure UHMWPE, but the wear resistance is better than that of pure UHMWPE. The optimum content of nano-CuO in composite is about 15% -17% .
