摘要
采用一种新型的分散方法促使纳米SiC在镀液中的均匀有效分布。初步探讨了工艺参数对复合镀层的影响,着重研究阴极电流密度对Ni-W-SiC纳米复合镀层表面形貌、断面形貌、n-SiC共析量和显微硬度的影响。结果表明:在其他工艺不变的条件下,选择适当的电流密度可制备出形貌良好、成分均匀、硬度较高的纳米复合镀层。
A new disperse method was applied to disperse n-SiC to avoid conglomerating. The effect of process parameters on the nano-composite coating was presented. The influence of cathodic current density on surface morphology, section morphology, n-SiC co-deposition amount and microhardness of nano-composite coating was mainly studied. The result shows that good morphology, n- SiC particle dispersed uniformly and highly microhardness value of nano-composite coatings can be prepared under proper current density when other process conditions are same.
