用电化学方法研究了锌在浓ＫＯＨ溶液中的电化学行为，得出了锌在浓碱液中的电化学反应机理。利用弱极化曲线拟合法得出了锌的腐蚀速率与ＫＯＨ浓度的关系。
The electrochemical behavior of pure zinc in concentrated KOH solution was studied using electrochemical techniques. It was found that the dissolution of zinc was accelerated and the evolution of hydrogen was inhibited in the anodic and cathodic Tafel region respectively with increasing concentration of OH-. Three relaxation processes were observed on EIS at the anodic polarization potentials. The corrosion mechanism of zinc in the alkaline solutions was advanced according to these experimental facts. The relation between the corrosion rate of zinc and the concentration of OH- was obtained by low polarization region curve-fitting technique.
