摘 要: 金属增材制造技术具有成型复杂结构构件、材料利用率高、制造周期短和力学性能好等优点,在生物医用、航空航天、军事等领域得到了广泛应用。然而镁合金由于具有化学性质活泼、熔沸点低和蒸气压较高等特点,使得对镁合金增材制造技术的研究远远落后于其他合金。本文综述了近年来国内外关于镁合金增材制造方面的相关文献,全面分析了适合镁合金增材制造的相关技术,讨论了增材制造工艺参数对镁合金成型质量、组织、力学性能和耐腐蚀性能的影响规律,并对增材制造镁合金的发展方向和亟需解决的问题进行了展望。

Abstract:The metal additive manufacturing technology was widely used in biomedical, aerospace, military and other fields because of its advantages in the forming complex structure components, high material utilization, short manufacturing cycle and good mechanical properties. However, the research on magnesium alloy additive manufacturing technology lags far behind that of other alloys due to the active chemical properties, low boiling point and high vapor pressure of magnesium. The relevant literatures on the magnesium alloy additive manufacturing in recent years were summarized in this paper, and the suitable technologies for magnesium alloy additive manufacturing were comprehensively analyzed. The influence of additive manufacturing process parameters on the forming quality, microstructure, mechanical property and corrosion resistance of magnesium alloys was also discussed. Finally, the development direction and problems that need to be solved urgently of additive manufacturing of magnesium alloys are prospected.
