The AC Impedence Technique Researches on the Process of Crevice Corrosion of 1Cr13 Stainless Steel

    Graphical Abstract
    • Abstract
  • The process of crevice corrosion of 1Cr13 stainless steel in neutral 3.5% NaCl solution has been studied by the AC impedance measurement technique. A special impedance measurement device was designal for this purpose.Through the imPedenCe measurement in situ of corrosion process, we have gained a new insight into the state of the samples interface within the crevice such as the adsorptional effect of the chloride ions etc.From the results,an anodic dissoluson equation was given as follows:
    Me2++mH2O+nCl-→MeCln (OH)m+mH+.
