摘 要: 金屬增材制造技術具有成型復雜結構構件、材料利用率高、制造周期短和力學性能好等優(yōu)點，在生物醫(yī)用、航空航天、軍事等領域得到了廣泛應用。然而鎂合金由于具有化學性質活潑、熔沸點低和蒸氣壓較高等特點，使得對鎂合金增材制造技術的研究遠遠落后于其他合金。本文綜述了近年來國內外關于鎂合金增材制造方面的相關文獻，全面分析了適合鎂合金增材制造的相關技術，討論了增材制造工藝參數(shù)對鎂合金成型質量、組織、力學性能和耐腐蝕性能的影響規(guī)律，并對增材制造鎂合金的發(fā)展方向和亟需解決的問題進行了展望。

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.
