Speech Title: New Materials and Methods to Monitor Corrosion
Abstract: Corrosion is a global problem causing accidents, failures and shutdown of the industries and oilfield reservoirs. The worldwide economic loss is enormous due to corrosion and still there is no proper solution to mitigate it. All the available methods can delay or mitigate the process of corrosion for some time but cannot stop it fully. Use of inhibitors is one of the available methods which are cheap, and easy to use. Modern methods play vital role in elucidating the mechanism of corrosion inhibition, the determination of corrosion rate, and elucidating the mechanism of corrosion inhibition. The talk will mainly focus on modern electrochemical techniques including Electrochemical Impedance Spectroscopy (EIS), Potentiodynamic Polarization (Tafel,) and Electrochemical Frequency Modulation (EFM) as an effective method to understand corrosion inhibition mechanism. To. explore additional information through electrochemical frequency modulation, new experiments were conducted to observe a trend with and without inhibitor. Modern methods are not complete without discussing the micro-electrochemical techniques including Scanning Electrochemical Microscopy (SECM), Scanning Kelvin Probe (SKP), Localised Electrochemical Impedance Spectroscopy (LEIS), and Scanning Vibrating Electrode (SVET) that provide the information about the localized electrochemical nature. Surface analyses are also important to confirm the mitigation phenomenon of the inhibitor. The importance of different methods including scanning electron microscopy (SEM), atomic force microscopy (AFM) and contact angle studies shall be highlighted to vindicate the mechanism of corrosion mitigation. Moreover, to confirm the data obtained from the experimental studies the significance theoretical studies such as including DFT and Molecular Dynamic studies will also be highlighted.
Keywords: EFM, Inhibitor, SVET, AFM, SKP, LEIS.
