Abstract

Corrosion behavior of AZ31 magnesium in tropical marine atmosphere was investigated. Chloride ions deposition rate played an important role in the corrosion process, which resulted in an obvious fluctuation of the corrosion rate. The corrosion was initiated from pitting corrosion and then evolved into general corrosion as the exposure time extended. Mg₅(CO₃)₄(OH)₂·xH₂O was the dominate products during the whole exposure periods. The products on the specimens weathered for 1, 6 and 12months slightly suppressed the corrosion process, while that generated after 24months of exposure exhibited good protective ability against further corrosion attacks.
