应用高能量密度等离子体对Ｆｅ３Ａｌ进行微晶化处理，在合金表面获得了晶粒尺寸介于１０～１００ｎｍ的微晶层。对比研究了铸态Ｆｅ３Ａｌ微晶处理前后在空气中１０００℃高温氧化的行为和规律，发现微晶化处理后，合金表面在氧化过程中形成了微晶氧化膜，极大地改善了氧化膜的塑性和粘附性，氧化速率显著降低，氧化动力学服从４次方规律。
The high-energy density plasma was used to micro-crystallize Fe3Al to obtain a microcrystalline layer with a grain size of 10-100nm on the surface of the alloy. The behavior and regularity of the as-cast Fe3Al crystallites before and after oxidation in air at high temperature of 1000 ℃ were compared. It was found that the microcrystalline oxide formed on the surface of the alloy after the microcrystallization, which greatly improved the plasticity of the oxide film And adhesion, the oxidation rate was significantly reduced, the oxidation kinetics obey the fourth law.
