摘　　要：本文采用了熔盐电解法研究铝钪合金的制备,主要考察了以MF-ScF3-ScCl3为电解质体系,以ScCl3为原料,制取铝钪合金的工艺条件,包括电流密度、电解时间以及电解温度等对反电动势、合金钪含量和电流效率的影响。研究结果表明,以MF-ScF3-ScCl3为电解质体系,以ScCl3为原料的熔盐电解法制备铝钪合金的钪的含量最高可达3.85%,电流效率达到73%。It is studied That preparation of A1--Sc alloy by molten salt electrolysis In this text. MF--ScF3 --ScCla as the electrolyte and ScCl3 as raw material , the processing condition of preparation of AI--Sc al-loy which include the influence of current density, electrolysis hour and temperature of electrolysis on EMF, content of Sc in alloy and current efficiency. With electrolysis hour prolonged, the current efficiency increases gradually, which it can reach to the maximum of 73% and the content of Sc in alloy which can reach to the maximum of 3.85 %.
