摘　　要：镁合金化学性质活泼,熔炼过程中易产生杂质,严重影响其力学和耐腐蚀等性能,需采取净化技术予以处理。文中介绍了镁合金熔体的熔剂净化和过滤净化、吹气净化、真空净化等在内的非溶剂净化技术的研究进展,并对镁合金熔体净化技术的未来发展作出了展望。Magnesium alloy exhibits the active chemical property. The inclusion is easy to occur during its melting process, which is harmful to the mechanical and corrosion-resistant properties. Thus, some purification treatments should be taken to reduce the amount of the inclusion. The paper introduces the current research development on the flux purification and the non-flux purification such as filter purification, gas bubbling purification, vacuum purification and so on of magnesium alloy melt. Meanwhile, the development prospect is forecasted.
