研究了多壁碳纳米管和碳化硅包覆铜增强铜基混合纳米复合材料的显微组织和摩擦性能。碳纳米管含量为1%~4%，碳化硅含量固定在4%。铜杂化纳米复合材料的合成过程包含球磨、冷压、烧结，随后热压。对混合纳米复合材料进行了密度、晶粒尺寸和硬度测试。在不同载荷条件下，在销?钢盘摩擦仪上采用干滑动磨损评估纳米复合材料的摩擦性能。结果表明，与纯铜相比，混合纳米复合材料的晶粒尺寸明显减小，4%碳纳米管增强杂化纳米复合材料的显微硬度提高了80%。混合纳米复合材料中碳纳米管含量的增加导致材料的摩擦因数和磨损率降低。
Microstructure and tribological properties of copper-based hybrid nanocomposites reinforced with copper coated multiwalled carbon nanotubes (MWCNTs) and silicon carbide (SiC) were studied. Carbon nanotube was varied from 1% to 4% with silicon carbide content being fixed at 4%. The synthesis of copper hybrid nanocomposites involves ball milling, cold pressing and sintering followed by hot pressing. The developed hybrid nanocomposites were subjected to density, grain size, and hardness tests. The tribological performances of the nanocomposites were assessed by carrying out dry sliding wear tests using pin-on-steel disc tribometer at different loads. A significant decrease in grain size was observed for the developed hybrid composites when compared with pure copper. An improvement of 80% in the micro-hardness of the hybrid nanocomposite has been recorded for 4% carbon nanotubes reinforced hybrid composites when compared with pure copper. An increase in content of CNTs in the hybrid nanocomposites results in lowering of the friction coefficient and wear rates of hybrid nanocomposites.
