| 摘 要： | 通过测量极化和分散能力,对以Watts型电镀Ni溶液为基础的几种溶液进行了研究,考察了NiSO4和NaCl含量的影响,并采用SEM和XRD方法对Ni沉积层形貌及其结晶择优取向进行了分析.结果表明,综合考虑电导率和极化度的乘积,是显著提升溶液分散能力的重要途径;电沉积Ni镀层表面形貌主要受控于溶液中阴离子种类和数量,其晶粒尺寸和择优取向受控于过电位.

| Abstract: | Electrical conductivity is a key factor for determining the variables during electrodeposition process. In this study, several electrolytes based on Watts bath have been measured by comparing electrochemical polarization and throwing power, and the morphology of Ni deposit has also been analyzed. The results showed that high value of electrical conductivity multiplying polarizability is of great importance for enhancing the throwing power of electrolyte, and the morphology of Ni deposit is mainly dominated by electrochemical factor. |

| Keywords: | electrical conductivity throwing power morphology of Ni deposite |
