- Abstract
Water vapour mixed with air (10 vol.% H2O) has little effect on the AISI 316L stainless steel oxidation under isothermal conditions at 800 and 900 °C. The oxide scale is composed of Q2O3 and Mn1.5Cr1.5O4 located at the external interface. Results show that the presence of water lowers the specimen's mass gain. At 1000 °C, the effect of water vapour on the scale structure is deleterious. In situ X-ray diffraction permits to show that the breakaway is due to iron oxidation starting after about 30 hours. This leads to an external Fe2O3 scale growth and an internal multilayered FeCr2O4 scale formation.
