    摘要:

    研究了高溫氧化對(duì)鐵基非晶Fe78Si9B13合金軟磁性能的影響。結(jié)果表明：非晶Fe78Si9B13合金帶材經(jīng)高溫氧化處理后，在其表面形成了一層厚度約為10 μm的高電阻率鐵的氧化物層； Fe78Si9B13合金高溫氧化磁化變得困難，且飽和磁感應(yīng)強(qiáng)度Bs由氧化前的Bs=1.42~1.46 T下降到氧化后的Bs=1.29~1.38 T。同時(shí)，對(duì)非晶Fe78Si9B13合金帶材經(jīng)高溫氧化處理后磁化困難的原因進(jìn)行了討論

    Abstract:

    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 mm 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
