High-temperature oxidation of 1.25Cr-0.5Mo steel in SO2
The oxidation kinetics of 1.25Cr-0.50Mo steel under different thermal cycling conditions in the range of 520–700°C in a 2000 ppm SO2-argon gas mixture have been studied by thermogravimetric techniques. The influence of the number of thermal cycles experienced by the specimen has been determined on the oxidation process. Characterization of the scales was performed by scanning electron microscopy, and it was found that the nature of the scale is a function of oxidation temperature.
