AbstractThe poor steam oxidation resistance of P92 steel limits its long term application in 620 degrees C double reheat ultra-supercritical steam boilers. Aluminizing has been considered as one cost-effective solution to improve the oxidation resistance of substrate alloys without significantly worsening their mechanical performance. A modified aluminising was developed to form a thin beta-FeAl layer on heat-resistant P92 steel under relatively lower temperatures. Oxidation behaviour of the layer and the P92 steel was probed in flowing pure steam vapour up to 500 h at 650 degrees C. An unstable Fe-rich oxide layer of over 100 mu m in thickness grew on the steel, whereas only an extremely thin (< 0.2 mu m) and stable alpha-Al2O3 scale grew on the beta-FeAl layer that ultimately evolved to FeCrAl solid solution phase during oxidation, implying great potentials of applying the beta-FeAl coating for protecting practical boiler tubing systems against oxidation.
