High Temperature Oxidation of Fe-18Cr-Nano Al2O3 ODS Steel in Humidified Atmospheres

Abstract:

One candidate material for boiler components in supercritical water gasification (SCWG) processes is oxide dispersion-strengthened steels (ODS), which can resist aggressive humidified atmospheres under high pressures and temperatures. The high-temperature oxidation resistance of ODS steel can be improved by adding nanooxide particles such as Al2O3. In this study, the corrosion resistance of Fe-18Cr ferritic ODS steel reinforced with different nanoAl2O3 between 0.5-3.0 wt% in a humidified atmosphere containing 80% H2O at 800 °C was investigated. The lump phase of chromium and nanoAl2O3 particles were dispersed on iron matrixes after sintering. Several pores occurred in the Fe-18Cr ODS matrix due to air entrainment during forming processes, but they decreased after reinforcing with the nanoAl2O3. Adding 0.5 wt% nanoAl2O3 decreased the porosity of the ODS steel by around 1.8 times. After the oxidation test for 10 hours, the mass gain of the ferritic ODS steel decreased by about 9 % when the nanooxide was added. Fe-Al-rich oxides were found with hematite and Fe-Cr spinel oxide layers, which increased the oxidation resistance of the ODS steel.
