New electrochemical techniques used in corrosion to monitor the efficiency in acidic medium

 The use of electrochemical techniques is corrosion is very important as it helps to understand the mechanism at the electrode surface in a particular solution. Electrochemical impedance spectroscopy (EIS) is the most traditional method used in electrochemistry to determine the electrode behavior. Electrochemical impedance spectroscopy provides valuable information about the Nyquist, bode and phase angle plots together. EIS was used to determine the efficiency of some corrosion inhibitors in the corrosive solution. Scanning electrochemical microscopy (SECM), and scanning vibrating electrode (SVET) were used to detect the localized electrochemical behavior of the different metal samples. Various concentration of inhibitors were used to detect the changes in the electrochemical nature. These variations in presence of inhibitors were used to calculate the inhibition efficiencies of the inhibitors. The study was carried on for electrochemical frequency modulation (EFM) and electrochemical frequency modulation trend (EFMT). Further, the polarization tests (Tafel) were done to determine the corrosion rate and inhibition efficiency of the inhibitor.
