采用化学复合镀方法,在基体铜片上进行Ni-P/纳米碳管复合镀.用金相显微镜、扫描电子显微镜、X射线衍射仪和显微硬度计等实验手段研究复合镀层的组织、结构和性能.结果表明:随着镀液中纳米碳管含量的增加,复合镀层表面的颗粒变小且密度增加;复合镀层的硬度随纳米碳管含量的增加而提高;此外,纳米碳管的加入,使镀层由非晶变成了纳米晶,促进了复合镀层的晶化.

The electroless Ni-P-carbon nanotubes composite plating was studied on the copper substrate. Metallurgical microscope, scanning electronic microscope, X-ray diffractometer and micro hardness tester were used to study the structure, constitution and performance of the electroless Ni-P-carbon nanotubes composite deposit. Experiential results show that, with the increment of carbon nanotubes content in electroless plating solution, the grain size on the sample surface decreases whereas the density of grains and the hardness for composite deposit increases. Moreover, adding carbon nanotubes not only improves the degree of crystallization for the composite deposit but also helps their transformation from the amorphous state to the nanocrystal state.
