采用Taylor-Ulitovsky方法制备了直径分别在6.3～28.0μm、20.2～28.0μm和14.0～35.2 μm之间的玻璃包覆非晶态FeCuNbVSiB,FeBSiCMn和CoNiFeSiB微丝.通过X射线衍射、扫描电镜、振动样品磁强计分别测试了玻璃包覆微丝的组织结构、微观形貌和磁性,研究了不同成分玻璃包覆磁性合金微丝的玻璃包覆层厚度、合金芯直径对微丝磁性能的影响.结果表明,玻璃包覆磁性合金微丝的磁性能的影响因素由大到小依次为:饱和磁致伸缩系数、微丝成分和微丝尺寸.轴向磁化时随着微丝直径及玻璃包覆层厚度的增大,3种微丝的径向饱和场强度降低,FeCuNbVSiB和FeBSiCMn微丝的轴向矫顽力先分别由508 A/m和390 A/m降低到486 A/m和278 A/m后再升高到2570 A/m和342 A/m,CoNiFeSiB微丝的轴向矫顽力由171 A/m降低到63 A/m.
