| Abstract Scope |
The aluminizing on cyclic-oxidation behavior of 304H stainless steel (hereinafter called 304HA ) was studied over the temperature range 650oC in dry and wet air (50% H2O(g)). The results showed that the cyclic-oxidation kinetics of 304HA in dry air followed the parabolic rate law, with its oxidation rates increasing with temperature. On the contrast, those of 304HA in wet air revealed an initial-stage of mass gain, followed by a second-stage of significant mass lose at all temperatures. Single scales formed in dry air consisted of an exclusive of Al2O3. Moreover, those formed in wet air consisted of an outer layer of iron oxides and an inner layer of FeAl2O3. |
