The effect of temperature on the composition of the corrosion film on iron in aqueous sodium hydroxide and borate solutions was investigated using surface enhanced Raman spectroelectrochemistry (SERS). Fe(OH){sub 2} and Fe{sub 3}O{sub 4} were observed in the prepassivation region, while Fe{sub 3}O{sub 4} and FeOOH accounted for most of the passivated film at 25, 60 and 95 C. Fe(OH){sub 2} was found to be a stable component of the corrosion film on iron at 95 C, which is contrary to recently published theoretical calculations.
