description <p>The rusting evolution of low carbon weathering steels with different Mn, Ni contents under a simulated environment containing chloride ions has been investigated to clarify the correlation between Mn, Ni and the rust formed on steels. The results show that Mn contents have little impact on corrosion kinetics of experimental steels. Content increase of Ni both enhances the anti-corrosion performance of steel substrate and the rust. Increasing Ni content is beneficial to forming compact rust. Semi-quantitative XRD phase analysis shows that the quantity ratio of α/γ*(α-FeOOH/(γ-FeOOH+Fe<sub>3</sub>O<sub>4</sub>)) decreases as Mn content increases but it increases as Ni content increases. Ni enhances rust layer stability but Mn content exceeding 1.06 wt.% is disadvantageous for rust layer stability. The content increase of Mn does not significantly alter the parameters of the polarization curve. However, as Ni contents increases, <em>E</em><sub>corr</sub> has shifted to the positive along with decreased <em>i</em><sub>corr</sub> values indicating smaller corrosion rate especially as Ni content increases from 0.42 wt.% to 1.50 wt.%.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.22.4.12844">http://dx.doi.org/10.5755/j01.ms.22.4.12844</a></p>
