采用电化学极化方法研究了Ｎｉ３Ａｌ和Ｐｔ电极在８００℃熔融（Ｎａ，Ｋ）２ＣＯ３中的腐蚀电化学阳、阴极极化特征．在熔融碳酸盐中，阳极极化是金属与ＣＯ２－３的氧化、阴极极化则是Ｏ２－与ＣＯ２－３的还原．金属的阳极溶解与Ｏ２－的阴极还原构成了金属腐蚀电化学的阳、阴极过程．
The electrochemical and cathodic polarization characteristics of Ni3Al and Pt electrodes in molten (Na, K) 2CO3 at 800 ℃ were studied by electrochemical polarization method. In molten carbonate, anodic polarization is the oxidation of metal with CO2-3 and cathodic polarization is the reduction of O2- with CO2-3. Metal anodic dissolution and O2- cathodic reduction constitutes a metal corrosion electrochemical positive and negative processes.
