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.
