dc.description.abstract | In this study, we demonstrate the strategic replacement of Mo with excess Cr in Fe-Cr alloys and report their corrosion resistances. To better understand pitting corrosion, the electrochemical properties of the passive films observed on different alloys (Fe-20Cr-2Mo and Fe-25Cr) were compared. Mo-free Fe-25Cr offered comparable or better pitting corrosion resistance than Fe-20Cr-2Mo during film breakdown, repassivation, and pit propagation stages. We investigated the reason for enhanced stability against pitting corrosion as a result of Mo exclusion in such alloys. Mo accelerated co-dissolution of Fe and Mo itself, consequently enriching Cr on the surface and ultimately promoting onset of passivity. | - |
