【摘要】 借助扫描电镜、电子探针和Ｘ射线衍射仪，研究了铬对镍基合金抗高温氧化性能的影响。结果表明，随着合金γ－相中铬浓度的增加，合金氧化增量降低，氧化膜结晶细化，提高了合金抗高温氧化性。更多还原

【Abstract】 The effect of chromium on oxidation-resisting performance at high tempera ture of Ni-based alloy has been studied by SEM, EMP and X-ray diffractometer. The results show that oxidizing increase of alloy descends and crystallization of oxide film becomes fine with the increase of the chromium contentration in γ-phase. The oxidation-resisting performance at high temperature of Ni-based alloy will be increased.更多还原
