Abstract In this paper, the nickel electroplating processes at different depositing temperature and different current density have been monitored using electrochemical noise technique, and two new indices, the electroplating noise energy ED and the deposit energy Ex, are derived respectively from the depositing noise and the crystal face work function (Wj) to characterize the nickel deposit. The results showed that ED changes oppositely with Ex, the preferred orientation growth of nickel crystal plane with lower Wj corresponds to the lower Ex and higher ED, ie. ED can be used as a measurement to evaluate the preferential orientation of nickel deposits.

电化学噪声能量与沉积结构的相关性研究

摘要 本文采用电化学噪声技术对不同沉积温度和不同电流密度下的镍电镀过程进行监测，分别从沉积噪声和沉积噪声导出两个新的指标，电镀噪声能量ED和沉积能量Ex。晶面功函数 (Wj) 来表征镍沉积物。结果表明，ED与Ex的变化方向相反，Wj较低的镍晶面的择优取向生长对应于较低的Ex和较高的ED，即。ED 可用作评估镍沉积物优先取向的测量方法。
