摘要
本文采用非水室温化学镀的方法制备了Tb-Fe-Co-B合金薄膜,并利用SEM、EDS、XRD和VSM分析了稀土Tb对镀层形貌、成分、结构和磁性能的影响。结果表明:稀土Tb的添加量在3 g/L时,镀层更趋于平整致密,镀速明显提高,而镀层结构并未有明显转变;但对镀层的饱和磁化率和矫顽力均有所提高。此外,通过600℃热处理可改变镀层的结构从而对合金的磁性产生较大的影响。
The Tb-Fe-Co-B thin films were prepared through a non-aqueous electroless plating method at room temperature. The structures and magnetic properties of Sm-Fe-Ni-B alloys were characterized using SEM, EDS, XRD and VSM analyses. The results indicated that the coating was smooth. The density, deposition rate were improved with 3 g/L of Tb solution. An amorphous of Fe-Co-B was changed with a microcrystalline state of Tb-Fe-Co-B. The saturation magnetization rate and coercivity were enhanced in the meantime. In addition, the structure could be changed to produce a greater effect on the magnetic al- loy at 600℃.
