Abstract

Through systematic long-term atmospheric exposure, the corrosion performance and protective mechanisms of rust layers on low-alloy structural steels in Xinjiang's arid climate were comprehensively evaluated. Results demonstrate that MnO₂ and MnFe₂O₄ can moderately enhance the compactness of the rust layer. However, the combined effects of strong wind-sand erosion and high diurnal temperature variations induce significant internal stresses within the rust layer, leading to crack formation. Notably, Cr alloying demonstrates superior corrosion mitigation effects through dual mechanisms: (1) catalytically facilitating the preferential formation of thermodynamically stable α-FeOOH, (2) generation of highly protective (FeCr₂O₄), Cr(OH)₃ and Cr₂O₃.
