镁合金熔炼保护气体研究现状和展望

摘要

Gas protection has a great advantage in melting of magnesium alloy, which became a hot spot to many researchers, this paper summarizes the kind of magnesium alloy melting protective gas, protection mechanisms and the advantages and disadvantages of each gas. This paper put forward the development trend of magnesium alloy melting replaceable protective gas based on these problems existing in protective gas.%气体保护法在镁合金熔炼过程中的优势明显，该方法成为众多研究者的热点，本文就此总结了目前镁合金熔炼保护气的种类、各自的保护机理及优缺点，根据目前镁合金熔炼保护气存在的一些问题，提出了镁合金熔炼替代保护气体的发展方向。
