摘要

增材制造是融合材料科学、机械自动化及信息技术的先进制造技术，在近 30 年的发展中，发挥着越来越重要的作用。激光金属沉积（Laser metal deposition，LMD）是基于定向能量沉积（Directed energy deposition，DED）的一种增材制造技术，在近年来受到广泛关注和研究。阐述了 LMD 技术的基本工作原理及系统组成，重点介绍 LMD 技术国内外研究进展及应用现状，列举了一些基于 LMD 的工艺技术开发及装备研发制造，指出了 LMD 技术在成形效率和成形精度、工艺稳定性及性能一致性等方面的不足。最后，总结了 LMD 技术未来的 5 个发展趋势：材料体系集约化、工艺参数系统化、成形过程高效化、设备集成智能化和应用领域广泛化。

Abstract

Additive manufacturing is an advanced manufacturing technology that combines materials science

machanical automation and information technology. It has played an increasingly important role in the past 30 years of development. Laser metal deposition (LMD) is an additive manufacturing technology based on directed energy deposition (DED)

which has received widespread attention in recent years. The basic operation principle and system composition of LMD technology were described. The research progress and application status of LMD technology at home and abroad were mainly introduced. Some LMD-based technology development and equipment manufacturing were listed. The shortcomings of LMD technology in forming efficiency

forming precision

process stability and performance consistency were pointed out. Finally

Five development trends of LMD technology were summarized : Intensification of material system; Systematic analysis of technological parameters; Improve forming efficiency; Intelligent integrated device control

Expansion of application areas.
