| Abstract: | 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. |
