摘要
用电化学方法研究了卤素离子引起铁腐蚀的差异．解释了Ｃｌ－、Ｂｒ－、Ｉ－引起铁孔蚀的顺序，发现Ｆ－对铁阳极过程的影响明显不同于其它卤素离子．通过络合效应和沉淀效应解释了Ｆ－和ＥＤＴＡ对铁孔蚀的抑制作用．
The differences of corrosion caused by halide ions on iron in alkaline media were studied by electrochemical metheds. The order of pitting corrosion caused by Clx,Br and I- on iron has been interpreted. It was found that the influence of F- on the anodic process of iron was remarkably different from that of other halide ions. The pitting corrosion inhibiting action of F- and EDTA was interpreted by complexing and precipitating effects.
