摘　　要：纳米碳管具有优异的力学、物理性能,被认为是一种理想的复合材料增强体。在介绍纳米碳管结构、性能和应用的基础上,主要总结与回顾了含纳米碳管镀层的制备方法(包括化学镀、电镀法)及复合镀层在高硬度、低摩擦因数和低磨损率、高耐磨性、高耐腐蚀性等性能方面的研究现状,并探讨了复合镀层的发展与应用前景。针对纳米碳管长径比大、反应活性低、表面曲率大导致易团聚、不易分散这一缺点,还介绍了常用的镀前表面改性等处理方法。CNT is considered to be a promising reinforcing material because of its unique mechanical and physical properties. After introducing CNT＇ s structure, properties and applications, the methods for preparation of CNTs composite coatings （including electroless plating and electrodeposition） and the current investigation of the CNT＇ s composite coating properties such as high hardness, high corrosion resistance, tribological behavior, and so on were summarized. Afterwards, the development and application prospect of the composite coating were also discussed. Some common nanotube pre-treatments were recommended to overcome the drawback of easy aggregation and difficult dispersion due to the peculiarities of large ratio of longitudinal axis length to diameter, chemical inertness and large surface curvature.
