| 摘 要： | 为解决对渗法制备镁-锶系合金时存在的问题,以SrCl2+CaCl2为熔盐电解质,以熔融镁-铝合金为阴极,采用熔盐电解法制备了Mg-6Al-0.2Sr-0.2Ca合金,研究了熔盐配比、电解温度及电解电压等电解工艺参数对电解过程的影响,确定了最佳制备工艺,并对制备合金的成分、显微组织、物相组成及金属的析出及传输过程进行了分析。结果表明:在镁-铝合金熔体中电解SrCl2+CaCl2可直接制备出镁-铝-锶-钙合金;当SrCl2与CaCl2物质的量比为1∶1时,熔盐具有良好的可电解性能,其适宜的电解温度为750℃,电解电压为4 V;制备的Mg-6Al-0.2Sr-0.2Ca合金中,锶和钙以Al4Sr、Al2Ca等形式存在于基体晶界处。
