| 摘 要： | 采用扫描隧道显微镜（ＳＴＭ）观察到在含ＣＯ２的ＮａＣｌ溶液中，纯铁表面的腐蚀为不均匀腐蚀，咪唑啉酰胺（ＩＭ）能够在ＣＯ２溶液中稳定吸附在钢铁的表面，当外加电位超过脱附电位时，ＩＭ发生脱附。

| Abstract: | The corrosion of pure iron in the CO2 solution with NaCl is a kind of localized corrosion in-situ observed by scanning tunnel microscope (STM). The addition of imidazoline amide(IM) in the CO2 solution, inhibited this kind of corrosion, which showed the adsorption of IM on the surface of pure iron is very stable. When the potential applied on the pure iron is over theadsorption potential, IM will desorb from the surface of iron, which is studied by the microcosmicand macrocosmic methods. |
