Abstract

[One of the important electrochemical techniques used to investigate corrosion is electrochemical impedance spectroscopy (EIS). It complements the potentiodynamic polarization (PDP) and linear polarization (LP) techniques used in corrosion studies and is nondestructive. EIS can be used to determine the appropriate potential scan rate to be used in PDP and LP and validate the results. After a brief introduction to EIS, experimental aspects and analysis, specifically to characterize corrosion, are described. Applications of EIS in metal corrosion in a variety of environments are illustrated. Coatings are often employed to protect a surface from corrosion. The effectiveness of coating in enhancing the corrosion resistance is frequently evaluated using EIS. Several circuits used to model the impedance data using equivalent electrical circuits are described. The identification of the circuit elements with the physical components or the processes is also explained. The future scope of the application of EIS to corrosion is outlined, and the main advantages and limitations of this technique are summarized.]
