摘要
增材制造技术在船舶装备制造领域极具发展前景,轻量化、低损耗的制造模式大大地提高了能源及材料利用率。受限于铝合金自身冶金特性和增材制造工艺,铝合金构件在增材制造过程中易产生气孔、开裂等冶金缺陷,影响船舶装备的质量安全和可靠性。本研究主要概述了船舶铝合金电弧熔丝增材、选区激光熔化和摩擦搅拌沉积三种增材制造工艺及冶金缺陷控制方面的研究现状及进展,并对船舶铝合金增材制造技术的未来发展方向进行了展望,为船舶铝合金增材制造技术的发展及铝合金构件的缺陷控制提供参考。
Additive manufacturing technology has great development prospects in the field of ship equipment manufacturing.The lightweight and low-loss manufacturing mode greatly improves energy and material utilization.However,due to the metallurgical characteristics of aluminum alloys and the additive manufacturing process,the aluminum alloy components are prone to metallurgical defects such as porosity and cracking in the additive manufacturing process,which seriously affects the quality,safety and reliability of ship equipment.In this study,we summarize the research status and progress of three main additive manufacturing processes(wire arc additive manufacturing,selective laser melting and additive friction stir-deposition) of ship aluminum alloys and the metallurgical defect control,and look forward to the future research direction of the additive manufacturing technology of ship aluminum alloys,so as to provide reference for the development of the additive manufacturing technology and defect control of ship aluminum alloy components.
