摘要
研究了EB-PVD制备的NiCrFe高温合金箔在1000℃下的恒温氧化行为。结果表明,EB-PVD制备的NiCrFe高温合金箔具有较好抗氧化性,氧化动力学曲线遵守抛物线规律。经1000℃×100 h氧化后,试样表面由类屋脊状的TiO2大尺寸颗粒和棱椎状的Cr2O3小尺寸颗粒组成,中间由约12μm的致密Cr2O3组成,基体内部伴有少量内氧化物(Ni,Fe)Cr2O4。
The oxidation behavior at 1000℃ of NiCrFe superalloy by EB-PVD was studied.The results show that the alloy has good oxidation resistance and the oxidation kinetics curves obey the parabolic power law.The alloy after 100 h oxidation at 1000 ℃ is composed of large size ridge-like TiO2 powder and small size pyramidal Cr2O3 powder at surface,a dense Cr2O3layer with about 12滋m in the middle and some small amount of internal oxide（Ni,Fe）Cr2O4.
