- 摘要:
- 以钛合金Ti6Al4V作为基体，采用电沉积技术制备了纳米SiC增强Ni-Co基复合材料。以复合材料中最高纳米SiC含量作为实验目标，通过极差分析对复合材料的制备工艺参数进行了优化，得到了最优工艺参数为：电流密度5 A/dm2、温度45 ℃、镀液中纳米SiC浓度10 g/L、pH 4.0。通过补充实验证实了最优工艺参数的正确性，结果表明：最优工艺参数下制备的复合材料表面质量良好，比较均匀地分布着微米级的孢状晶粒，其中纳米SiC含量约为3.18 %。
- Abstract:
- Nano-SiC reinforced Ni-Co based composite material was prepared on the surface of titanium alloy Ti6Al4V substrate. The highest content of nano-SiC in the composite material was selected as the experiment target, and the process parameters for preparation of the composite material were optimized through range analysis. The optimal process parameters were determined as follows: current density 5 A/dm2, temperature 45 ℃, nano-SiC concentration in plating bath 10 g/L, pH 4.0. Supplementary experiment was carried out to verify the correctness of the optimal process parameters. The results showed that the composite material prepared with the optimal process parameters possessed good surface quality, micron-size spore grains were distributed uniformly, and the content of nano-SiC in the composite material was about 3.18 %.
