中文摘要：
研究了高温氧化对铁基非晶Fe78si9B13合金软磁性能的影响。结果表明：非晶Fe78si9B13合金带材经高温氧化处理后，在其表面形成了一层厚度约为10μm的高电阻率铁的氧化物层；Fe78si9B13合金高温氧化磁化变得困难，且饱和磁感应强度BS由氧化前的BS=1．42-1．46 T下降到氧化后的占BS=1．29～1．38 T。同时，对非晶Fe78si9B13合金带材经高温氧化处理后磁化困难的原因进行了讨论。
英文摘要：
The influence of high-temperature oxidation on soft magnetic properties of Fe78Si9B13 amorphous alloy was investigated using various analysis methods. The results reveal that a 10 μm thick iron oxide layer with high resistivity can be obtained on the surface of Fe78Si9B13 amorphous ribbons by high temperature oxidation treatment. It is found that the amorphous alloy magnetization becomes harder and the saturation induction density changes after the high-temperature oxidation. The saturation induction density value changes from Bs=1.42-1.46 T without chemical oxidation, to Bs=1.29-1.38 T after high-temperature oxidation. The factors which have a great effect on the magnetization difficulties of the amorphous ribbons were discussed.
