Review: General Study on Aluminum Corrosion Behavior in Artificial Seawater

Al and its alloys have a low atomic weight and high strength to density ratio.These properties make them very useful for the construction of parts in automotive industry, such as engine blocks or pistons.Al is prone to corrosion, due to its negative standard E of 1.66 V vs. NHE.In addition, Al corrosion resistance strongly depends on pH.Therefore, it is important to undertake a general study of Al corrosion behavior.
