摘　　要：镍基-碳纳米管复合镀层是将不同含量的碳纳米管和镍通过电化学沉积的方法共同沉积在中碳钢基质中。在没有添加任何润滑油的情况下,采用销-盘摩擦磨损试验机对复合镀层进行了摩擦磨损试验,结果显示,摩擦因数和磨损率都随着碳纳米管含量的升高而逐渐下降,耐磨性能显著提高。Ni-based carbon nanotube（CNT） composite coatings with different volume fraction of CNTs were deposited on medium carbon steel substrates by electro-chemical deposition. The friction and wear behavior of the composite coatings were investigated using a pin-on-disk wear tester under unlubricated condition. The experimental results indicate that the friction coefficient and wear rate of the composite coatings decrease with increasing the volume fraction of CNTs, and the wear resis＇tance is enhanced greately.
