Abstract
Atmospheric corrosion behavior of pure Al 1050A, 5A02 and 6A02 aluminum alloys exposed to a tropical marine environment for 4 years was investigated. Synergetic effect of Cl- deposition rate and time of wetness resulted in an abnormal increase in weight loss and a significant fluctuation in corrosion rate. Pitting corrosion occurred on the three metals. Pits on 5A02 alloy were easy to initiate and inclined to propagate laterally to form higher corrosion area and shallower corrosion pits, while pits on 6A02 alloy presented the opposite appearances. This was further confirmed by the cyclic polarization experiments.
