摘要
进入21世纪,金属材料成形技术正在发生巨大变革。电弧增材制造技术,因具有加工速度快、材料利用率高、成本低等优点,被尝试用于加工各种重要零部件。目前,以熔化极气体保护焊(GMAW)、钨极惰性气体保护焊(GTAW)、等离子电弧焊(PAW)为主,同时结合机器人、计算机仿真模拟、剖分算法、路径规划、工艺参数优化、后处理及组织与性能之间的内在联系等,以减少缺陷,适应不同性能指标需要。综述了电弧增材制造的工艺过程及其在镁合金中的研究现状,展望了镁合金电弧增材先进制造技术及智能化制造的未来发展方向。
Entering 21 st century,metal materials forming technology is revolutionizing greatly.Arc additive manufacturing technology,due to its advantages of fast processing speed,high material utilization rate and low cost,has been tried to be used to process various important parts.At present,gas metal arc welding(GMAW),gas tungsten arc welding(GTAW),plasma arc welding(PAW)are mainly used in additive manufacturing(AM).At the same time,the robot,computer simulation,subdivision algorithm and path planning optimization,process parameters,post-processing,and the internal relationship between microstructure and performance,etc.,to reduce defects,to meet the needs of different performance indicators.In this paper,the process of arc additive manufacturing and the research status of arc additive manufacturing in magnesium alloys are reviewed,and the future development direction of advanced arc additive manufacturing technology and intelligence for magnesium alloys is prospected.
