Magnesium (Mg) and its alloys are the lightest structural metallic materials with a high strength/weight ratio, which makes them desirable materials in the transportation industry. However, the widespread use of Mg alloys remains limited by their poor corrosion resistance. Electrochemical impedance spectroscopy (EIS) has emerged as a highly applicable in situ electrochemical technique used in Mg corrosion research due to its “non-destructive” character, and its capability to provide information on the electrode/electrolyte interface. This paper includes a brief review of some basic aspects of EIS. In addition, we discuss various applications of EIS techniques in the study of Mg corrosion.
