Resumo
Anodizing is a well-documented surface treatment that is inserted in a complex protection
system against corrosion applied to Al alloys. In the scientific literature, there are many
works about this topic, which are concentrated on: (1) anodic aluminum oxide (AAO)
growth mechanism; (2) anodized alloys corrosion behavior, or (3) the influence of anodizing
parameters on the following steps of corrosion protection of the anodized layer. However,
the effect of the microstructure on the AAO formation is not yet well established. This paper
aims to review the effect of the microstructure of Al and its alloys on the anodizing process
by a historical, statistical, and electrochemical approach, considering the advantages in
understanding the influence of intermetallics in this process. Besides, this review brings a
comparison among the number of publications and the types of alloys studied by statistical
analyses. Finally, it emphasizes the importance of anodizing in the aeronautical industry, in
which a great number of studied alloys are applied, mainly the 2XXX (Al-Cu) and 7XXX (AlZn) series alloys.
