采用循环伏安法、方波伏安法和计时电位法分别研究了Lu（III）在LiCl-KCl和LiCl-KCl-MgCl 2熔体中的电化学行为。在钼电极上进行恒电流电解以制备Mg-Lu合金，而在镁电极上进行恒电位电解以制备Mg-Lu合金层。采用XRD和SEM-EDS对镀层的微观结构和微区分析进行了表征。恒电流电解法制备了MgLu金属间化合物，合金层中存在Mg 24 Lu 5和MgLu两种金属间化合物以及Lu金属。
In the present work, the electrochemical behaviors of Lu (III) ions in molten LiCl–KCl and LiCl–KCl–MgCl2were investigated by cyclic voltammetry, square wave voltammetry, and chronopotentiometry, respectively. Galvanostatic electrolysis was conducted on a molybdenum electrode to prepare the Mg–Lu alloys, while potentiostatic electrolysis was conducted on a magnesium electrode to prepare the Mg–Lu alloy layers. The microstructure and microzone analysis of the obtained deposits were characterized by XRD and SEM–EDS. An intermetallic compound of MgLu was formed by galvanostatic electrolysis, whereas two kinds of intermetallic compound (Mg24Lu5and MgLu) and Lu metal in the alloy layer.
