摘要: 應用高能量密度等離子體對Fe₃Al進行微晶化處理,在合金表面獲得了晶粒尺寸介于10~100nm的微晶層。對比研究了鑄態Fe₃Al微晶處理前后在空氣中1000℃高溫氧化的行為和規律,發現微晶化處理后,合金表面在氧化過程中形成了微晶氧化膜,極大地改善了氧化膜的塑性和粘附性,氧化速率顯著降低,氧化動力學服從4次方規律。

Abstract: High energy density plasma technique(HEDP) was applied to surface treatment of Fe₃Al. A micro-crystalline layer with grain sizes between 10 and 100nm was obtained. Isothermal oxidation at 1000℃ in air for cast Fe₃Al before and after micro-crystallizing was studied. The results showed that for the micro-crystalline Fe₃Al,(1) a micro-crystalline oxide scale formed during oxidation;(2) the plasticity and adhesion of oxide scale was remarkably improved;(3) the oxidation rate was decreased;(4) the oxidation kinetics obeyed the forth power equation law.
