“…The corrosion protection abilities of Al alloys are too low for them to be used as industrial products for long-term applications because the corrosion of Al alloy products causes the deterioration of their performances and safeties. Therefore, surface treatments, including anodizing, chemical treatments, organic coating, metal plating, and thermal spraying, are applied to improve the corrosion protection of Al alloy products [7][8][9][10].…”
