摘要
镁合金具有比强度、比刚度高,阻尼性好,电磁屏蔽能力、抗辐照能力强等优点,是特别适合航天器选用的轻质金属材料。文章针对航天器结构轻量化的发展需求,结合镁合金在航天器中的不同应用情况,分析了镁合金存在的耐腐蚀性、焊接和加工成型等工艺问题,给出了具体工艺方法和措施建议。
Magnesium alloy is a kind of light metallic material,which excels in high specific strength and specific stiffness,good damping property,good properties in electromagnetic screening,and anti-irradiation performance,so it is widely used in spacecrafts.This paper analyzes the bottlenecks in processing magnesium alloy,such as the corrosion resistance,the welding,the machining and shaping.The problems and risks of the magnesium alloy applications in spacecrafts at different conditions are discussed,together with related process methods and proposals.
