The research on sacrificial anode corrosion of aluminum alloy focuses on materials. Corrosion damage is multifaceted, not only leads to material damage, aluminum alloy sacrificial anode and environmental damage. For example: food or wine production, storage and transportation process of container materials, due to corrosion caused by container wall thickness thinning, strength reduction, aluminum alloy sacrifice anode but at the same time may also lead to food or wine by corrosion product pollution and quality reduction. Although the latter is caused by corrosion, the change of the medium environment is generally called pollution, rather than corrosion prevention.

Sacrificial anodic corrosion of aluminum alloys is a reaction between the material and the environment, in many cases an electrochemical reaction.
