Potentiostatic Dechlorination of Simulated Cast Iron Artifacts

Abstract:

The corrosion and preservation of archaeological iron are affected by many factors, among which the role of chloride ions is particularly important. Chloride ion migration and the choice of optimized potential during potentiostatic dechlorination of simulated cast iron artifacts in alkaline solution were studied by means of potentiostatic polarization. The results showed that the more treatment time and the more negative of the potential, the more was the extraction ratio of chloride ion and the less was the electrical efficiency. The potential was optimized with respect to the extraction ratio of chloride ion and the electrical efficiency, and the optional potential was presented.
