Abstract
The aim of this research focused on obtaining an understanding of the role of chromium in a binary iron aluminides in aqueous environments, i.e. 0.25 M sulfuric acid. Using a binary Fe-26Al and X8 CrNiS 18-9 alloy for comparison purposes, electrochemical potentiodynamic polarization was undergone. All three alloy demonstrated a change on oxide during passivation. The addition of chromium demonstrated the highest corrosion current density yet the lowest and widest passivation range.
