摘要

该文主要研究了DMF中电化学制备Ce-Fe-Co合金薄膜材料，利用电化学工作站对Ce（Ⅲ）、Fe（Ⅱ）和Co（Ⅱ）在铜电极表面的电化学行为进行了研究，并利用EDS、SEM、XRD、VSM等仪器对镀层的化学组成、结构和性质进行了测试。结果表明：① Ce不能单独沉积到电极表面

但Co和Fe的沉积可以诱导Ce沉积；② 沉积电位对合金的化学组成影响最大，其次是镀液组成和沉积时间；③ Ce的加入提高了合金的磁性能；④ 高温退火后合金向晶态转变，晶体成规则的球型结晶，磁性能降低。

Abstract

Various Ce-Fe-Co alloys were prepared in DMF. Electroreduction behaviors of Ce (Ⅲ)，Fe (Ⅱ) and Co (Ⅱ) on Cu electrodes were studied using electrochemical workstation. Their chemical composition

structure and property were analyzed by EDX

SEM

XRD and VSM analyses. The results demonstrated that (1) Ce (Ⅲ）was not reduced to deposit on the surface of electrode

but deposited by deposition of Co and Fe; (2) Deposition potential strongly affected chemical composition of alloys

but the effect of bath composition and deposition time was weak; (3) Magnetic property of alloys was increased by adding Ce; (4) The spherical crystal formed with the increase of annealing temperature

resulting in decrease of magnetic property.
