摘要

合成了4个2-硫代海因衍生物，并采用失重、动电位极化、电化学阻抗谱等方法评价了它们在0.5M盐酸溶液中对低碳钢(MS)的缓蚀性能。采用扫描电子显微镜(SEM)和原子力显微镜(AFM)对金属表面形貌进行了表征。研究表明，这些化合物对低碳钢在酸性介质中的腐蚀具有良好的保护作用。

ELECTROCHEMICAL INVESTIGATION OF 2-THIOHYDANTOIN DERIVATIVES AS CORROSION INHIBITORS FOR MILD STEEL IN ACIDIC MEDIUM

Four 2-thiohydantoin derivatives were synthesized and their corrosion inhibition properties on mild steel (MS) in 0.5M HCl solution was evaluated using usual gravimetric and electrochemical methods (weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS). Morphology of the metal surface was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The study has shown that these compounds provide good protection for mild steel against corrosion in the acidic medium.
