OXIDATION OF PURE Ce AND Fe-Ce ALLOY UNDER LOW OXYGEN PRESSURES
纯Ce及Fe—Ce合金在低氧压下的氧化

the oxidation of pure Ce and Fe-Ce alloy containing 15% Ce (mass fraction) at low oxygen pressures was studied at 600 -800C . After oxidation pure Ce produced outer Ceq scale, but Fe-15Ce alloy produced rapidly internal oxidation of Ce .?he micmtmctures of the regions of internal oxidation follmd closely the of the original alloys, while no cerium depletion was observed around the internal oxidation front.
