摘要
利用气相反应法在 Fe- Cr- Al电热合金表面原位生成了耐高温的绝缘膜。绝缘膜主要由α- Al2 O3相组成 ,膜的绝缘性良好 ,生长符合抛物线规律。另外研究了表面质量、氧压、反应时间及合金元素等因素对绝缘膜击穿性能的影响。
In this paper,the in-situ forming of insulating film by gas-reaction on Fe-Cr-Al alloy for heating conductor is discussed. It is found that the film consists of α -Al 2O 3 mainly and is a good insulation, and its growth conformes to parabolic rule. Several factors that have an effect on breakdown characteristics of insulating film are also investigated.
