Corrosion of Aluminum Alloys in Exfoliation-Resistant Tempers Exposed to Marine Environments for 2 Years

Abstract

The corrosion behavior of 5086, 5083, and 5456 aluminum alloys in H116 and H117 tempers was evaluated after 2 years of exposure to three marine environments; namely, fully submerged in sea water, splash and spray zone, and marine atmosphere. The alloys displayed good corrosion resistance with no exfoliation or pitting observed. Panels of the same alloys in a sensitized condition exposed to the same environments showed some pitting and edge attack but did not indicate a long-term corrosion problem.
