AB Understanding the interaction between cyclic stresses and corrosion of magnesium (Mg) and its alloys is increasingly in demand due to thecontinuous expansion of structural applications of these materials. This review is dedicated to exploring the corrosion-fatigue mechanisms ofthese materials, with an emphasis on microscale processes, and the possibility of expanding current knowledge on this topic using scanningelectrochemical techniques. The interaction between fatigue and corrosion of Mg alloys is analyzed by considering the microstructural aspects(grain size, precipitates, deformation twins), as well as the formation of pits. Furthermore, in the case of coated alloys, the role of coatingdefects in these phenomena is also described. In this context, the feasibility of using scanning electrochemical microscopy (SECM), scanningvibrating electrode technique (SVET), scanning ion-selective electrode technique (SIET), localized electrochemical impedance spectroscopy(LEIS) and scanning Kelvin probe (SKP) methods to study the corrosion-fatigue interaction of Mg alloys is examined. A comprehensivereview of the current literature in this field is presented, and the opportunities and limitations of consolidating the use of these techniques tostudy the microscale processes involved in Mg corrosion-fatigue are discussed.
