Abstract The characteristics of the microstructure, the electrochemical properties and the application of the high potential magnesium sacrificial anodes are summarized. The effect of impurity elements,Ca,Sr,Mn elements and the new process in melting and casting on the microstructure and the electrochemical properties of the magnesium anodes,the effect of Zn contents on the electrochemical performance of Mg-Zn super high potential magnesium anode, and the manufacturing process,application of as-extruded magnesium anodes are analyzed. In addition, the existing problems and the development tendency are put forward in this paper.
