Abstract
It is well-known that high strength aluminum alloy 2024 has high mechanical strength but poor corrosion resistance. The Al-Cu intermetallic compound particles exposed on aluminum alloy 2024 matrix are detrimental to corrosion. We have shown that the Al-Cu intermetallic compound particles exposed on high strength aluminum alloy 2024 are selectively removed. It is found that the intermetallic compound-free surface is preferable for the surface treatment such as Zn plating. Zinc has a function as sacrificial anode because zinc is less noble than aluminum.
