Copper matrix composites with carbon nanotubes/Cu composite foams as the reinforcing skeletons (CNTs/Cu_f®Cu) were prepared by electrodeposition and spark plasma sintering. The microstructure and tribological properties of the composites were studied. The CNTs reinforcements with the content up to 0.283 vol% remained uniformly distributed in the skeleton zone and led to quite different structure and properties as compared to the pure copper zone. Significant reduction of the friction coefficient and wear rate was shown with CNTs reinforcements in the skeleton up to a certain content. The wear surface morphology was analyzed and the possible wear mechanism was discussed for the composites with such an inhomogeneous structure.

用碳纳米管/ Cu复合材料泡沫体作为增强骨架（碳纳米管/铜铜基质复合材料_˚F ®Cu）通过电沉积和放电等离子烧结。研究了复合材料的微观结构和摩擦学性能。与纯铜区相比，含量高达 0.283 vol% 的 CNTs 增强剂在骨架区保持均匀分布，并导致完全不同的结构和性能。碳纳米管增强体在骨架中达到一定含量后，摩擦系数和磨损率显着降低。分析了磨损表面形貌，并讨论了具有这种不均匀结构的复合材料可能的磨损机制。
