在舍有Fe~(2+)的离子液体1-丁基-3-甲基四氟硼酸盐([BMIM]BF_4)电解液中,研究了金属铁的电沉积工艺.讨论了镀液组成及工艺条件对镀层外观质量的影响,确定了较佳的电镀工艺条件.在该工艺条件下,得到了结晶细致、外观均匀、光亮的金属铁镀层.稳态极化曲线测试表明:在[BMIM]BF_4-Fe(BF_4)_2体系中,铁的电沉积是受扩散控制的非可逆电极过程.扫描电子显微镜(SEM)观察镀层的微观形貌显示金属铁的结晶细小.XRD分析证实:镀层为纯铁,沉积的铁的结晶发生明显的择优取向.

The electrodeposition of metallic iron from [BMIM]BF_4 ionic liquid containing Fe~(2+) was investigated on coppersubstrates. The influences of bath composition and operation conditions of the process on the appearance of iron coatings were discussed, and the optimum technological conditions determined, under which a bright, appearance-uniform and fine coating was obtained. The polarization curve indicates that the electrodeposition of metallic iron in the [BMIM] BF_4-Fe (BF_4)_2 electrolyte is controlled by diffusion and irreversible growth process. SEM images of the iron deposits show that the crystallite is small and compact. X-ray diffraction(XRD) analysis approves that the obtained deposits are of pure Fe, and the grains have a preferred orientation along (110) crystal plane.
