采用电沉积工艺制备了不同成分的铁镍合金镀层,分析了镀层的微观形貌及组织结构,并测量了电沉积样品的磁化曲线和磁滞回线。研究结果表明:通过电沉积工艺可得到晶体结构的铁镍合金层,不同成分的铁镍合金层织构取向有所不同;镀层的磁性能随镍含量的变化而变化,在开路测量条件下的最大磁导率高于冷轧态1J85合金。

Different composition FeNi films were prepared through electrodeposition. The surface morphology and structure of films were analyzed. The magnetization curve and magnetic hysteresis of samples were measured. The results indicate that the Fe-Ni films with crystal structure can be prepared through electrodeposition. The Fe-Ni films of different chemical compositions possess different preferred orientation. The magnetic performances vary with Ni mass fraction. The maximum permeability of electrodeposited Fe-Ni films is superior to the cold-rolled 1J85 alloy in open circuit measurement.
