摘　　要：利用化学镀方法制备镍基纳米碳管复合镀层,用扫描电镜分析了镀层的表面形貌,并用销-盘式磨损试验机研究了复合镀层在干摩擦条件下的摩擦磨损行为.结果表明:纳米碳管均匀地嵌入在镍基体中,镍基纳米碳管复合镀层具有优良的耐磨性能;由于纳米碳管的自润滑作用,复合镀层的摩擦系数随着纳米碳管体积分数的增加而逐渐降低.Ni-based carbon nanotubes (CNTs) composite coatings were prepared by electroless plating. The surface morphology of the coatings was analyzed by a scanning electron microscope (SEM). The friction and wear behavior of the composite coatings were investigated using a pin-on-disk wear tester under dry sliding condition. The experimental results indicated that the carbon nanotubes were uniformly embedded the composite coatings, and the Ni-based CNTs composite coatings showed excellent wear resistance. Due to the self-lubrication of carbon nanotubes, the friction coefficient of the composite coatings decreased with the increasing volume fraction of carbon nanotubes.
