| 摘 要： | 研究了Fe78Si9B13非晶合金磁芯进行环氧封装及封装后对非晶合金磁芯软磁性能的影响。结果表明对磁芯进行环氧封装,有效改善磁芯的机械强度同时,能改善带材表面的平整度,在带材表面形成一层绝缘层,显著降低了非晶合金磁芯高频下的损耗值,封装后的非晶合金磁芯在Bm=1T,f=1kHz下,损耗值比封装前下降了14%。综合考虑机械强度大小、磁化难易、损耗高低等因素,封装胶浓度为2%时封装效果最佳。

| Abstract: | The coating with epoxy on Fe78Si9B13 amorphous alloy magnetic core and its influence on soft magnetic properties were studied.It is found that the core’s mechanical strength and the strip’s flatness are improved after coating.At the same time,a insulation layer of coating can be formed on the surface of the strip.The coatings play significant roles in decreasing the core loss of amorphous alloy magnetic cores at high frequencies.After coating,the core loss of amorphous alloy magnetic cores decreased by 14% at Bm=1T,f=1kHz.Considering the factor such as mechanical strength,magnetization,and core loss,the coating achieves best as the ratio of coating adhesive is 2%. |
