摘　　要：利用电化学阻抗谱(EIS)技术研究了含有锌铬黄防锈颜料的环氧酯漆涂层的耐蚀性能。研究发现,当老化时间为4周时,涂层的耐蚀性能最佳,时间过长或过短都使得涂层性能下降。并且EIS技术可以用来研究涂层的老化。The corrosion resistance of an epoxy coating containing the pigment of zinc chrome yellow was studied using electrochemical impedance spectroscopy (EIS). The results showed that the coating had the best performance when it was aged for 4 weeks. However, when the aging time was longer or shorter, the coating would exhibit bad anti-corrosion performance. Electrochemical impedance spectroscopy could be used in the study of aging coating.
