AbstractIn this article, the rusting evolution of 690 MPa grade multifunctional construction structural steel was investigated under a simulated industrial atmospheric environment. The corrosion product stabilization process was examined using the corrosion mass loss method, electrochemical measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), and electron probe microanalysis (EPMA). The results indicated that the corrosion kinetics exhibited a two-stage process, including a rapid stage followed by a slow stage. The initial sharp rise in corrosion rate was related to the involvement of reducible corrosion products in the cathode reduction process, which accelerated the dissolution of the anodic steel substrate. The appearance of the inflection point in the corrosion stage was strongly associated with the accumulation of corrosion products. As the corrosion time progressed, the corrosion products changed from porous to compact structures because of the synergistic effects of Cu, Ni, and Cr. This compact, thick, and uniform rust layer was identified to contain aggregates of crystalline gamma-FeOOH along with a large number of fully grown flowery-shaped alpha-FeOOH on its top. Thus, the corrosion resistance increased when the rust layer gradually accumulated, and the diffusion of the corrosive ions was obstructed owing to the inhibited electrochemical corrosion. After a prolonged dry-wet cyclic corrosion, the rust layer led to stress cracking, but its self-repairing ability would make the cracks die.
