Pure Fe, Cr and Fe-Cr binary alloys were corroded in O-2 containing 298 ppm KCl vapour at 750 degrees C. The corrosion kinetics were determined, and the microstructure and the composition of oxide scales were examined. During corrosion process. KCl vapour reacted with the formed oxide scales and generated Cl-2 gas. As O-2 gas introduced the active oxidation, a multilayer oxide scales consisted of an outmost Fe2O3 layer and an inner Cr2O3 layer formed on the Fe-Cr alloys with lower Cr concentration. In the case of Fe-60Cr or Fe-80Cr alloys, monolayer Cr2O3 formed as the healing oxidation process. However, multilayer Cr2O3 formed on pure Cr. (C) 2009 Elsevier Ltd. All rights reserved.
