The influence of the low-temperature pre-oxidation by ozone on the corrosion resistance of T91 steel in a steam environment at 600 °C was investigated. XRD, SEM, EDS and XPS were employed to characterize the corrosion products. Results show that the corrosion kinetics of the studied materials obeyed the parabolic oxidation law. Thin (Fe, Cr)2O3 oxides were developed on the surface of T91 after pre-oxidation by the ozone at 150 °C. The low-temperature ozone pre-oxidation improved the oxidation resistance of T91 steel in steam, which can possibly be applied to industrial application.
