摘要 研究了稀土元素Ce、Nd对NiAl- 2 8Cr- 5 5Mo - 0 5Hf合金高温氧化性能的影响,并通过扫描电镜和能谱分析研究了氧化产物的微观组织与成分.结果表明:稀土的加入改变了表层氧化膜中各氧化物的含量。 The effect of rare earth elements Ce and Nd on the oxidation resistance of NiAl-28Cr-5 5Mo-0 5Hf alloy has been studied in the paper.The microstructure and composition of oxide layer have been studied by means of X-ray diffractometer and scanning electron microscope with an EDAX unit. The results show that the addition of rare earth elements changes the content of the constituent scales in the surface scale, eliminates internal oxidation and reduces mass gain of the oxide.
