Abstract
With regards to localized corrosion, the role of uniform corrosion of aluminum alloys has not always been accounted for in the past. The impact of uniform corrosion on aluminum alloys 2024-T3, 6061-T6, and 7075-T6 is studied here to provide quantitative evidence of its importance. Preliminary weight loss experiments combined with optical profilometry (OP) indicate that corrosion attributed to uniform corrosion is very significant when compared to localized corrosion. A series of free immersion tests were conducted to understand the influence of environmental variables including temperature (20, 40, 60, 80
