摘要: 用电化学测试技术研究了碱性溶液中卤素离子对铁阳极过程的影响。结果表明,相同条件下卤素离子对铁阳极钝化膜的破坏作用顺序为:Cl~->Br~->I~-。F~-对Cl~-引起的铁孔蚀有明显的抑制作用,可能是由于F~-能与Fe~(3+)形成稳定而难溶解的FeF_3配合物。

Abstract：The influence of halide ions on anodic process of iron in alkaline solutions has been studied by electrochemical techniques. The results show that the breakdown potential of passivated film on iron in halide containing solution becomes more positive in the following order Cl~-→Br~-→I~-. The obvious inhibition effect of F~- ion on pitting of iron causedby Cl~- ion was observed. This effect could be explained by the formation of stable, insol uble complex FeF_3.
