Abstract

The corrosion mechanisms of pitting, intergranular corrosion, and general corrosion were examined on an AE44 magnesium alloy subjected to immersion and salt-spray environments. The two environments show similar trends with respect to weight loss and thickness loss, although the immersion environment induces greater amounts of weight loss of magnesium. With respect to the corrosion mechanisms, the two environments show definitive trends, owing to the continuous presence of water in the immersion environment allowing more and larger pits to form as compared to the salt-spray environment. The immersion environment was more deleterious than the salt-spray environment for magnesium.
