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．
Electrochemical methods were used to study the difference of iron corrosion induced by halogen ions. Explained the order of Cl-, Br- and I- causing iron pitting, and found that the effect of F- on iron anodic process is obviously different from that of other halogen ions. The inhibitory effect of F- and EDTA on iron pitting corrosion was explained by complexing effect and precipitation effect.
