交流阻抗技術對不銹鋼縫隙初探腐蝕過程的研究

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

  • 摘要: 本文通過自行設計的阻抗測量裝置,首先將交流阻抗時域測量技術應用于不銹鋼縫隙腐蝕過程的研究,從而實現了對縫隙腐蝕過程的瞬時測量。實驗得到了1Cr13不銹鋼在縫隙腐蝕過程中不同極化時間的阻抗圖。獲得了縫隙腐蝕過程中有關氯離子在電極表面發生吸附、破壞等隨時間的變化細節,并與縫內微區溶液成分的微電極現場監測數據相吻合。據此我們提出了不銹鋼發生縫隙腐蝕的溶解方程式為:

     

    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+.
