对CVD法制备的碳纳米管进行了表面改性和修饰,然后通过化学共沉积方法制备了高硬度的碳纳米管复合镀层,并研究了碳纳米管复合镀层在不同摩擦组合下的摩擦学行为.结果表明:经过改性处理后的碳纳米管表面拥有丰富的表面官能团,这使大量的碳纳米管复合于镀层中,从而导致了镍磷复合镀层的硬度显著提高,达到946 HV.摩擦实验得出,在润滑状态下以钢环为摩擦副,碳纳米管增强的镍磷复合镀层比传统耐磨材料SiC增强的镍磷复合镀层具有更低的摩擦系数和磨损率.此外,不同摩擦组合下的摩擦结果表明,SiC复合镀层相互摩擦时尽管拥有较低的磨损率,但其摩擦系数仍然较高,而碳纳米管复合镀层相互摩擦时表现出最低的摩擦系数和磨损率,其摩擦系数和磨损率分别为0.108 7和1.49×10-3 g/m.
