Fe73.5 Cu1 Nb3 Si13.5 B9纳米晶带材具有优异的软磁性能，在开关电源等领域得到广泛的应用，但Fe73.5 Cu1 Nb3 Si13.5 B9纳米晶带材磁芯在封装过程中存在着环氧树脂严重的不浸润问题，限制了纳米晶带材的应用。通过氧化处理法在带材表面制备了分布均匀、表面光洁、黑棕红色 Fe3 O4和 Fe2 O3氧化膜，氧化膜与带材结合力强，可以作为带材基体与环氧树脂的过渡层，改善了环氧树脂与带材的浸润性。相对于未表面氧化处理的带材，经过表面氧化处理带材的初始磁导率、饱和磁感应强度分别提高了14.6%和4.3%，矫顽力降低了21.6%。

Fe73.5 Cu1 Nb3 Si13.5 B9 nanocrystalline strip exhibit excellent soft magnetic properties,and was widely used in the field of switch power supply,etc.But Fe73.5 Cu1 Nb3 Si13.5 B9 nanocrystalline strip magnetic core exis-ted serious infiltration problem of epoxy resin in the process of encapsulation,which limited the application of nanocrystalline strip.We invest the oxidation process on the surface of the strip.The surface of the strip dis-tribute uniformity,smooth,dark red brown oxide film.With strong binding force with the strip,oxide film could be use as a transition layer of strip matrix and epoxy resin,so it could improve the infiltration between the strip and epoxy resin.Compared with the strip without surface oxidation treatment,the initial permeability and saturated magnetic induction intensity of the strip with surface oxidation treatment increased by 14.6% and 4. 3% respectively,and the coercive force was reduced by 2 1 .6%.
