96.53% Mg, 0.27% Li and 3.20% Gd (mass fraction). Then, the reduction of lithium ions occurs quickly. The composition of alloy can be adjusted by controlling electrolysis time or Gd2O3 concentration.... The distribution of Gd element in Mg-Li-Gd alloys indicates that Gd element mainly distributes at the grain boundaries of Mg-Li-Gd alloys. Key words: electrochemical codeposition; Mg-Li-Gd alloy; chloride melt......
氯化物熔盐体系共电沉积法制备Mg-Li-Gd合金的研究魏树权1,2,张密林1,韩伟2,颜永得2,张斌2(1.黑龙江省哈尔滨市哈尔滨工程大学材料科学与化学工程教育部超轻材料与表面技术重点实验室2.黑龙江省哈尔滨市 哈尔滨师范大学化学化工学院)摘 要:在LiCl-KCl-MgCl2-Gd2O3熔盐体系中采用电化学共沉积法制备Mg-Li-Gd合金,借助循环伏安和计时电位技术对熔盐电化学行为进行探讨,并运用XRD,SEM,EDS和OM对所得合金进行测试.研究结果表明,Gd2O3在LiCl-KCl熔盐体系中几乎不溶,而在LiCl-KCl-MgCl2熔盐中有一定的溶解度,而且随着温度的升高,Gd2O3的溶解度也随之增大.循环伏安和计时电位研究表明,添加MgCl2和Gd2O3后,Li的沉积电位向正向移动,当阴极电位小于......
