摘要

应用极化曲线和交流阻抗技术研究了 4种缓蚀剂在N80钢基体和碳酸亚铁膜上的吸脱附行为 .实验表明 ,对同一种缓蚀剂 ,其在N80钢光洁表面和在腐蚀产物膜上的吸附力强度不同 ,而酸性缓蚀剂和小分子缓蚀剂在N80钢光洁金属表面和碳酸亚铁膜上各表现出不同的缓蚀行为

Abstract

The de_adsorption behavior of four inhibitors on N80 steel with and without carbonate film was investigated by polarization and electrochemical impedance spectroscopy (EIS) techniques. It was found that,for different inhibitors,de_adsorption behavior and adsorbability between with and without carbonate film are different.Furthermore,acidic inhibitor and small size molecule inhibitor shows different inhibition behavior.
