摘要	Corrosion behaviour of the high-strength galvanized steel wires under tensile stress was researched by electrochemical polarization and salt spray test (SST) using simulated acid rain as electrolyte. Electrochemical polarization and SST results showed corrosion rate rose significantly with increasing tensile stress; white grains were observed by SEM after polarization, while cellular and dendritic crystals appeared on the rust layer after SST. XRD and TG-DTA results revealed (Zn(OH)2)3?center dot?ZnSO4?center dot?5H2O was the main corrosion product, and traces of Fe2(SO4)2O?center dot?7H2O, Fe2(SO4)3, Fe2O3?center dot?H2O were also detected. A three-stage corrosion process for the galvanized steel wires during SST was proposed.
