| 摘 要： | 在流动的高浓度锌酸钾碱液中研究了镍箔和镀镍冲孔钢带基体电极对锌沉积/溶解电化学行为的影响.结果表明,在流动电解液中电极表面浓度梯度变化不大,不同基体上均未出现锌沉积的阴极峰；扫描速度超过10 mV/s,循环伏安曲线基本不随扫速变化,说明锌的沉积/溶解峰电流不仅与扫描速度有关,还取决于锌沉积的时间.采用镀镍冲孔钢带基体兼...

| Abstract: | The effects of substrates including nickel foil,nickel-plated perforated steel strip,on deposition/dissolution behavior of zinc from flowing concentrated alkaline zincate solutions were investigated.The results show that almost no changes of concentration differences occur in flowing electrolytes,leading to no cathodic peaks appearing in cyclic voltammograms.At a scan rate above 10 mV/s,no variation of voltammograms for the zinc deposition/dissolution with scan rate is observed.This indicates that zinc depo... |
