CORRELATION BETWEEN POTENTIAL--TIME CURVES OF CONSTANT--CURRENT ANODIC DISSOLUTION AND CORROSION RESISTANCE OF TINPLATE
镀锡钢板耐蚀性与恒电流阳极溶解电位-时间曲线的关系

The potential-time curve of anodic dissolution of tinplate by constant-current electrolysis in hydrochloric acid solution with relatively high current density has been used as a tool for the characterization of corrosion resistance of tinplate products. Three pattern recognition methods, including SVM (support vector machine), PCA (principal component analysis) and Fisher method have been used for modeling the relationship between E-t curve and ATC (alloy-tin couple) values describing the corrosion resistance of tinplate samples. The obvious correlation between E-t curves and ATC values implies that it may be possible to find a quick method useful for monitoring and optimal control of the quality of tinplate in industrial production.
