通过电化学测试和表面表征，研究了锡在含氯薄电解层中的腐蚀行为。结果表明，在腐蚀初期，随着电解液层厚度的减小，腐蚀速率增大。在相同电解液层厚度下，腐蚀速率随曝光时间的延长先增大后减小。在后期，由于溶解的金属离子扩散困难，在50和100Kμm的薄电解液层下的阳极过程受到抑制。锡表面形成的腐蚀产物由锡和锡氧化物及氢氧化物组成。
The corrosion of tin under thin electrolyte layers containing chloride was investigated by electrochemical measurements and surface characterization. The results show that the corrosion rate increases as the electrolyte layer thickness deceases in the initial stage. Moreover, the corrosion rate under the same electrolyte layer thickness increases firstly and then decreases with the exposure time. In the later stage, the anodic processes under thin electrolyte layers of 50 and 100 μm are inhibited due to the difficult diffusion of dissolved metal ions. The corrosion products formed on tin surface are composed of stannous and stannic oxides and hydroxides.
