摘　　要：利用动电位扫描法研究了咪唑啉缓蚀剂MCI在碳钢表面成膜的耐蚀性能 ;通过电化学交流阻抗技术 .测量了碳钢表面成膜的EIS谱 ,并提出其特征等效电路 .探讨了缓蚀剂在碳钢表面的缓蚀机理 .实验结果表明 。Corrosion inhibition performance of surface film formed on carbon steel induced by imidazoline inhibition MCI was studied by potentiodynamic polarization technique.Electrochemical Impedance Spectroscopy(EIS) of the MCI induced film on the surface of carbon steel was measured and an equivalent circuit was proposed.The relation between impedance characteristics and the corrosion inhibition mechanics of MCI was discussed.The results showed that the MCI-treated carbon steel has good corrosion resistance during high-temperature and high-pressure test.
