THE MECHANISM RESEARCH OF CORROSIVE PROMOTIONOF H~+AND CI~-ON IRON
酸度和氯离子浓度对工业纯铁腐蚀的促进作用机制研究

The polarization curves of iron in the solutions with diffirent concentrations ofH+ and CI-- are measured. The corrosion parameters of iron are obtained. It is showed that,inthe solutions with high concentrations of H+ and CI--, the anodic process of iron is not apparentlyaffected by CI--, and it can accelerates the HER of cathodic process as increasing itS concentrations. H+ can accelerate the anodic process of iron as increasing itS concentrations.The mechanismof anodic process and HER process are suggested,the r. d. s of HER is Volmer reaction.
