摘要：
Dynamic Electrochemical Impedance Spectroscopy (DEIS) has been used as an effective method for determining information about corrosion and inhibitor systems. Thus, it has been successfully applied to investigate the formation mechanism of pitting corrosion, the damage mechanism occurring over time in organic coatings, the cavitation caused by corrosion detection and the monitoring of the battery discharging process. This method has been suggested as an effective and useful tool for establishing the time of the best inhibition activity. In this study, benzotriazole (BTA) was used as a corrosion inhibitor for St37 steel in a 0.1MHCl environment. Consequently, the advantage of using DEIS to determine the electrochemical changes occurring over time with the addition of an inhibitor was demonstrated.
