摘要：
In this study, the corrosion behavior of AlMn lightweight weathering steel (LWS) in the simulated marine atmosphere was investigated by means of the dry/wet corrosion cycle test. The results showed that Al was present as FeAl2O4 and enriched in the inner layer, which significantly optimizes the rust layer in terms of compactness, elemental distribution, phase constitution, and electrochemical properties. The Mn oxides promoted the formation of FeAl2O4 and enhanced the anti-rupture ability of the LWS's rust layer.
