摘　　要：在酸性镀液中电沉积了Fe Zr B纳米合金。讨论了影响镀层组分的因素。用原子吸收光谱和分光光度法分析了镀层组分 ,线性扫描和循环伏安法研究了电极过程。实验结果表明 ,甘氨酸和二甲基甲酰胺 (DMF)抑制了铁的沉积 ,沉积机制可能是诱导共沉积。电镜扫描图像表明镀层粒子是纳米粒子 ,XRD分析表明镀层含有FeFe Zr B nanocrystalline alloys were electrodeposited in an acid bath. The factors that affect the deposit composition were discussed. Atomic absorption spectrum and spectrophotometry were employed to analyse the compositions of the deposits. Linear sweep voltammetry (LSV) and cyclic voltammetry (CV) were used to study the process of electrodeposition. Experimental results indicate that glycine and N,N dimethylformamide (DMF) hinder the deposition of iron. The mechanism maybe induce co electrodeposition. Scanning electron microscopy image shows there are nano particles and X ray diffraction showes the presence of Fe Zr alloy.
