| 摘 要： | 用交流阻抗、阴极充电曲线和俄歇能谱研究了十八胺在铁表面的成膜，结果表明十八胺渗透到氧化铁层成膜，使电极表面的阻抗值增大，提高了电极的耐蚀性，经质量浓度为２５ｍｇ／Ｌ的ＯＤＡ处理液处理的电极具有最佳的耐蚀性。

| Abstract: | The iron samples treated with ODA are studied by using AC impedance spectroscopy, cathodic charging curves and Auger electron spectroscopy. The results reveal that ODA penetrates into iron oxide layers and increases the impedance values of the electrodes. The sample treated with 25 mg/L ODA has the best anti-corrosion performance. The structures of surface layers of ODA-treated samples are as follows: at lower ODA concentrations: iron?iron oxide?mixed ODA-iron oxides and at higher ODA concentrations: iron?iron oxide?mixed ODA-iron oxides?ODA. |
