| description | This study investigates the influence of chloride ion concentrations on the initial corrosion behavior and product evolution of 3 % Ni weathering steel, with a focus on understanding the limitations of nickel's corrosion resistance in high-chloride environments. Accelerated wet-dry cyclic corrosion tests were performed, and the results were analyzed using XRD, XPS, SEM, TEM, and first-principles calculations. The findings reveal that 3 % Ni weathering steel exhibits limited corrosion resistance during the initial stages, with corrosion products predominantly composed of non-protective γ-FeOOH and β-FeOOH. Nickel, initially uniformly distributed, was observed to localize within β-FeOOH regions but failed to form an effective protective layer. Computational results demonstrate that chloride ions significantly inhibit the transformation of γ-FeOOH to α-FeOOH, while the persistence of β-FeOOH is kinetically controlled. These mechanisms collectively weaken the corrosion resistance imparted by nickel. This study highlights the importance of initial corrosion behavior as a criterion for the rapid screening and design of weathering steels and provides valuable insights into improving their performance in marine environments. |
