通过电化学测试和表面分析，研究了在含有3.5wt.%氯化钠的模拟混凝土孔溶液中加入阳离子型咪唑啉季铵盐型缓蚀剂对钢筋的缓蚀性能。结果表明，IQS能显著提高钢筋的极化电阻和点蚀电位，降低钢筋的腐蚀电流密度。主要的缓蚀机理可能是由于缓蚀剂在钢筋表面的吸附，导致钢筋的腐蚀电流密度降低。(C)2014爱思唯尔有限公司。保留所有权利。
In this study, the corrosion inhibition performance of steel reinforcement in the simulated concrete pore solution containing 3.5 wt.% NaCl in the presence of a tailored cationic type of imidazoline quaternary ammonium salt corrosion inhibitor was characterized by electrochemical measurements and surface analysis. The results indicate that the IQS can significantly improve the polarization resistance and pitting potential and reduce the corrosion current density of reinforcement. The main inhibition mechanism is most likely due to the adsorption of the corrosion inhibitor on the steel surface, leading to a reduced corrosion current density of the steel reinforcement.
