The corrosion of magnesium anode is mainly due to the presence of second phase in the magnesium anode caused by alloy and impurity elements. The chemical corrosion of magnesium anode is mainly affected by pH value of solution, nature of solution, composition of alloy and environment. Its corrosion forms mainly include galvanic corrosion, pitting corrosion, stress corrosion cracking, intergranular corrosion, filiform corrosion and high temperature oxidation.

In order to improve the service life of magnesium anode materials, we can choose to improve the corrosion resistance of magnesium anode, such as alloy elements, impurity elements, phase composition and microstructure. The research on the surface treatment technology of magnesium anode also brings some vitality to improve the corrosion resistance of magnesium anode. Some people choose to use ion implantation, laser annealing and rapid solidification technology to form a uniform and amorphous surface structure film on the metal surface.
