| Abstract: | The corrosion behavior of iron at 900°C in gas mixtures of O2/N2, H2O/O2/N2, HCl/H2O/O2/N2, H2O/N2, and HCl/H2O/N2 was observed. Parabolic oxide-scaling kinetics were observed in all cases, except HCl/H2O/N2 containing 2.5% HCl. This gas produced linear weight-loss kinetics caused by FeCl2 vaporization. Lower HCl concentrations in H2O/N2 led to no chloride formation. In all cases, the reaction products reflected a close approach to local equilibrium between scale and gas. The presence of H2O led to oxide-scale-surface faceting, and in the presence of free oxygen, to acceleration of the sublayer growth of FeO. |
