    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.
