摘　　要：介绍了一种通过溶胶-凝胶法在铁基纳米晶带材表面制备TiO2薄膜的方法,并研究了涂层后对带材的磁性能影响。结果表明,通过溶胶-凝胶法可在带材表面形成一层TiO2薄膜;带材表面变得光滑、平整;涂层后带材的有效磁导率下降,品质因数增加,软磁性能下降;提拉2次得到的薄膜对带材磁性能影响最小。Iron-based nanocrystalline ribbons surface was coated with thin films of TiO2 by sol-gel method and its influence to magnetic properties are studied.The results show that a layer of the TiO2 can be formed on the surface of the ribbons by sol-gel method.After coating,the surface of ribbons become smooth,but effective magnetic permeability decreases when quality factors increases,the soft magnetic properties decreases.The thin films get at 2 times of dip-coating create minimum effect to magnetic properties of ribbons.
