摘要
镁合金作为最有发展前景的轻质结构材料之一,具有良好的铸造性、可加工性、生物相容性和优异的力学性能,已广泛用于汽车制造、航空航天以及生物医学等多个领域。随着轻量化发展,开发镁合金整体构件已成为其应用趋势。但是,整体构件通常具有规模大、结构复杂的特点,相较于传统制造工艺,电弧增材制造具有沉积速率高、成本低、材料利用率高等特点,为制备大型镁合金构件提供可能性。因此,镁合金电弧增材制造得到了不同程度的研究,本文主要从3个方面对镁合金电弧增材制造的研究进展进行综述。首先,介绍了电弧增材制造技术不同工艺方法;其次,介绍了镁合金电弧增材制造的研究现状包括成型质量和组织性能;最后,总结了镁合金电弧增材制造可能面临的挑战,为镁合金电弧增材制造技术的进一步研究与应用提供参考。
As one of the most promising lightweight structural materials,magnesium alloys have excellent castability,machinability,biocompatibility and excellent mechanical properties,and have been widely used in many fields such as automotive manufacturing,aerospace,and biomedicine.With the demand onlightweight,the development of magnesium alloy integral components has become an emerging trend.However,the integral components usually have the characteristics of large scale and complex structure.Compared with traditional manufacturing processes,wire and arc additive manufacturing has the characteristics of high deposition rate,low cost,and high material utilization rate,providing the possibility to prepare large magnesium alloy components.Therefore,the wire and arc additive manufacturing of magnesium alloy has received a lot of attentions.This article mainly summarizes the research progress in wire and arc additive manufacturing of magnesium alloy from three aspects.Firstly,different process methods of wire and arc additive manufacturing technology are introduced;secondly,the research status of wire and arc additive manufacturing of magnesium alloy is introduced,including molding quality,microstructure and properties;finally,the possible challenges faced by magnesium alloy wire and arc additive manufacturing are summarized,providing a reference for further research and applications of magnesium alloy wire and arc additive manufacturing technology.
