摘要
在LiCl-KCl-MgCl2电解质中加入Pr6O11,电沉积Mg-Li-Pr合金,实验条件:温度650℃,电流密度11A.cm-2,Mg2+与Li+摩尔比1∶9.1,研究了稀土镨对合金的微观组织及性能的影响。SEM及EDS分析表明Mg,Pr在合金中均匀分布。XRD、金相显微照片和显微硬度分析表明,在合金中镨以Mg3Pr的形式存在,随着镨的含量的增加,Mg-Li合金由α相转变为β相,同时晶粒的细化更加明显,机械性能得到提高。
The electrodeposition of Mg-Li-Pr alloy in LiCl-KCl-MgCl2 molten salt with the addition of Pr6O11 was studied at temperature of 650 ℃ with cathodic current density of 11 A .cm^-2 and Mg^2＋ （mol）/Li^＋ （mol） ratio of 1 ： 9.1. SEM and EDS analysis results indicated that magnesium and praseodymium elements evenly distributed throughout the alloy. It was found that the Mg-Li alloys gradually changed from α phase to β phase with the increase of praseodymium content, and the phase of Mg3Pr was also observed in the alloy deposit by X-ray diffraction. The fine grain and im- proved mechanical property were observed by optical microscopy and microhardness instrument.
