利用电化学阻抗(EIS)技术研究了含有锌铬黄防锈颜 料的环氧树脂涂层的耐蚀性能.研究发现，在老化时间一定的情况下(672小时)，老化温度越 高，涂层的耐蚀性能越差，但比不进行老化的涂层耐蚀性能好.并且该技术可以用来研究涂 层的老化.
The investigation of corrosion resistance of epoxy c oating containing pigment of zinc chrome yellow was made using electrochemical i mpedance spectroscopy(EIS) measurement.The results indicated that the corrosion resistance of the coating may be enhanced through aging treatment,which reached an optimum after aging at 80℃ for 672 hours.However,aging treatment at above 8 0℃ for the same peried,the corrosion resistance then decreased.It was indicated that EIS could be used to evaluate the effect of aging on the coating.
