    摘要:

    激光增材制造技术是一种革命性的先进制造技术,在航空航天、汽车、医疗等领域取得了快速发展和应用。然而,采用激光增材制造技术成形金属时容易形成气孔、裂纹等缺陷,以及粗大柱状晶、成分偏析等组织问题,影响了金属的性能。通过添加纳米陶瓷颗粒能够有效地改善合金成形性、细化组织,进而提高金属力学性能。本文从激光增材制造成形金属时纳米陶瓷颗粒的添加方式,纳米陶瓷颗粒在熔池中的演化行为,纳米陶瓷颗粒对成形性、微观组织和力学性能影响几个方面进行了论述,并对该领域存在的问题和未来的研究进行了总结和展望。

    Abstract:

    Laser additive manufacturing is a revolutionary advanced manufacturing technology that has rapidly developed and been applied in fields such as aerospace, automotive, and medical. However, when using LAM to form metals, it is easy to form defects such as pores and cracks, as well as microstructural issues such as coarse columnar crystals and composition segregation, affecting the performance of the metal. The addition of nano-ceramic particles can effectively improve alloy formability, refine microstructure, and thereby enhance mechanical properties of the metal. This research discussed the addition method of nano-ceramic particles during laser additive manufacturing of metals, the evolution behavior of nano-ceramic particles in the molten pool, and the impact of nano-ceramic particles on formability, microstructure, and mechanical properties. The existing problems and future research in this field were also summarized and prospected.
