In addition, the substrate metal surface layer associated with the surface, and substances in the ambient medium that can affect the medium/metal interface. From the thermodynamics to reduce the energy of the interface, from the dynamics to increase the interface to reflect the required resistance or activation energy, so that the most direct and effective erosion reaction on the interface. They also directly or indirectly affect the erosion process on the interface, and adjusting them can also play a controlling role.

Since erosion is a chemical action on the surface of the material, the core of corrosion prevention should be to change the interface between the magnesium alloy and the environment. 

Therefore, the surface anti-corrosion strategy of magnesium alloy is essentially to reduce the activity of the interface reaction between magnesium alloy and environmental media and improve the activation energy of the interface reaction.
