以LiCl KCl为电解质 ,铝为阴极 ,在 45 0℃下采用熔盐电解法直接制取铝锂母合金 ,并研究了熔盐电解法生产铝锂合金的工艺条件。结果表明 :随着电流密度、电解时间的适当增加 ,合金中锂的含量逐渐增加 ;但是过大的电流密度和过长的电解时间会导致阴极出现开裂现象 ,使工艺条件不稳定 ,影响产品质量。 With LiCl KCl as electrolyte and aluminum as cathode, the Al-Li alloy was directly prepared by molten salt electrolysis at 45 0 C and the technological conditions of Al-Li alloy production by molten salt electrolysis were studied. The results show that with the appropriate current density and electrolysis time, the content of lithium in the alloy gradually increases; however, too large current density and too long electrolysis time will lead to cracking of the cathode, which will make the process conditions unstable and affect the product quality .
