Benefit of the rust layer formed on AlMn lightweight weathering steel in industrial atmosphere
Graphical abstract Display Omitted
Highlights Rust layer of AlMn lightweight weathering steel is more resistant to corrosion. The existence form of Al element in the rust layer was mainly FeAl2O4. Mn changes the content of FeAl2O4 and α-FeOOH in the form of MnO/MnO2.
Abstract The rust layer of AlMn lightweight weathering steel in industrial atmosphere was investigated through rust layer analysis (structure, phase composition and elemental distribution) and electrochemical measurement. The rust layer of lightweight weathering steel exhibits superiority in terms of structure, phase composition and distribution, and electrochemical properties. The enrichment of FeAl2O4 in the inner rust layer refine the rust grain, promotes the transformation of γ-FeOOH to α-FeOOH, increases the compactness of the rust layer, and produces an electronegative inner rust layer to block the S element. Mn changes the content of FeAl2O4 and α-FeOOH in the form of MnO/MnO2, which affects the corrosion resistance of lightweight weathering steel.
