    应用动电位扫描法和交流阻抗法研究了盐酸介质中KI和癸胺对铝的协同缓蚀作用.结果表明:铝在盐酸中的腐蚀以阴极控制为主;KI和癸胺有较好的协同作用,癸胺在协同体系中对铝的缓蚀起主导作用.

    The corrosion inhibition behavior of decylamine or/ and iodine ion for aluminum in hydrochloric acid solution was studied by polarization curves and electrochemical impedance spectroscopy (EIS).The results showed that cathodic reaction controlled the corrosion of aluminum mainly;Decylamine and I- exhibited good synergistic effect and decylamine played the main factor of the inhibition in the synergistic system.
