摘要
利用电化学阻抗谱 (EIS)方法研究高绝缘性能防护层 /碳钢试片体系 ,测定阴极极化电位下 4种常用防护层的EIS谱图 .分析它们在 0 6mol/LNaCl溶液和土壤中的阻抗谱特征 ,研究结果表明 ,Bode图及电化学等效电路解析得到的防护层电容 (Cf)值可用来对防护层质量进行表征 .
Four kinds of perfectly insulated coating systems in common use was studied by electrochemical impedance spectroscopy(EIS).Their EIS characteristics under cathodic polarization potential in 0.6 mol/L NaCl and in soil respectively were analyzed.We tried to obtain evaluating method for coating quality.The study result demonstrated that the Bode figure and the C f value obtained according to equivalent circuit for the corrosion behavior of a polymer-coated metal could be used to evaluate coating quality.
