| 摘 要： | 采用负载于铝粉上的镍催化剂，成功地在650℃通过化学气相沉积法在钳基体中原位合成碳纳米管。结构农征表明，所合成的碳纳米管具有较高的石墨化程度和平直的石墨壳层。通过该方法实现铝粉中碳纳米管的弥散分布，其分散效果优于传统机械混合方法。利用所合成的碳纳米管／铝原位复合粉末，采用粉末冶金工艺制备碳纳米管／铝基复合材料。性能测试表明，制备的复合材料的力学性能和尺寸稳定性得到显著提高，其原因在于铝基体中碳纳米管的均匀分散和碳纳米管－铝基体之间良好的界面结合。

| Abstract: | Using nickel catalyst supported on aluminum powders, carbon nanotubes （CNTs） were successfully synthesized in aluminum powders by in-situ chemical vapor deposition at 650 ℃. Structural characterization revealed that the as-grown CNTs possessed higher graphitization degree and straight graphite shell. By this approach, more homogeneous dispersion of CNTs in aluminum powders was achieved compared with the traditional mechanical mixture methods. Using the in-situ synthesized CNTs/Al composite powders and powder metallurgy process, CNTs/Al bulk composites were prepared. Performance testing showed that the mechanical properties and dimensional stability of the composites were improved obviously, which was attributed to the superior dispersion of CNTs in aluminum matrix and the strong interfacial bonding between CNTs and matrix. |
