摘　　要：通过室温化学镀方法制备Tb-Fe-Ni-B合金薄膜材料,利用SEM、XRD、VSM等仪器对Tb-Fe-Ni-B合金镀层结构及性能进行了检测和分析。结果表明,与非晶态的Fe-Ni-B合金镀层相比,在氩气氛围内不同温度下热处理60 min后,该镀层转变为含有FeNi_3、Fe_3B、Fe_(4.5)Ni_(8.5)B_6、Ni_4B_3、NiB_3、Tb_3Ni_3B_2、Fe_2Tb、TbNi_2的晶型结构。铽的加入有效提高镀层的平整性,经热处理后,微晶结构的Tb-Fe-Ni-B合金镀层具有较高的饱和磁化强度和磁导率,较低的剩余磁化强度和矫顽力,显示出了良好的软磁性能。Tb-Fe-Ni-B thin films were prepared with ethanol solvent through electroless plating at room temperature. The structure and properties of the alloys were measured by means of SEM,XRD and VSM. The results show that,comparing with amorphous Fe-Ni-B alloy,the coating is transformed into crystalloid FeNi_3,Fe_3B,Fe_（4.5）Ni_（8.5）B_6,Ni_4B_3,NiB_3,Tb_3Ni_3B_2,Fe_2Tb and TbNi_2after heating treatment for 60 min in argon atmosphere. The Tb-Fe-Ni-B alloy coating on the surface of copper is smoother and more homogeneous than Fe-Ni-B. The microcrystalline Tb-Fe-Ni-B alloy presents much higher saturated magnetic intensity and magnetic permeability and much lower remainder magnetic intensity and coercive force. Therefore,this kind of alloy coating exhibits favorable soft magnetization.
