| 摘 要： | 电化学体系中电位及电流的周期性振荡现象早有发现,对于这些振荡行为的解释多数均涉及到金属的钝化或过渡钝化及固体盐膜的生成1,2].本文采用旋转圆盘电极研究了铁在浓NaCl溶液中阳极溶解时的电位振荡行为,并试图应用非保护性多孔膜的生成和溶解以及Fe2+的扩散过程来说明这些现象。

| Abstract: | The galvanostatic potential oscillations during anodic dissolution of iron in concentrated chloride media were investigated.The minimum currents which caused the oscillations were observed.The periods of oscillations were affected by the rotation rates of the electrode, electrolyte concentration and current densities.It was considered that the form and dissolution of FeCl2 and Fe(OH)2 film were the cause of potential oscillations.For the oscillations with stationary electrode, the imposed current densities were inversely proportional to the square root of the periods, which was consistent with the result by analysing the diffusion equation. |
