Abstract The superior oxidation resistance of oxide dispersion-strengthened FeCrAl-base alloys is due to the formation of a slowly growing alumina scale on the surface. In this study, the growth mechanism of oxide scale formation on yttria-dispersion FeCrAl alloy with and without Pt doping was studied during oxidation at 1200℃ in air. The morphologies of the alumina scales and compositions of the oxides on the surface of the FeCrAl alloys were different. Pt doping disturbs the growth mechanism of the oxide scale formation at the initial stage, and the element diffusion mechanisms of oxide formation on the ODS-FeCrAl alloys are discussed.

Pt掺杂对1200℃氧化钇弥散FeCrAl合金氧化皮形成的影响

摘要 氧化物弥散强化的 FeCrAl 基合金优异的抗氧化性是由于在表面形成缓慢生长的氧化铝氧化皮。本研究在空气中1200℃氧化过程中，研究了掺杂和不掺杂Pt的氧化钇弥散FeCrAl合金氧化皮的生长机制。FeCrAl合金表面氧化铝鳞片的形貌和氧化物成分不同。Pt掺杂在初始阶段扰乱了氧化皮形成的生长机制，讨论了ODS-FeCrAl合金氧化层形成的元素扩散机制。
