摘要

激光熔化沉积（LMD）是一种典型的增材制造技术，与传统的成形工艺相比，具有加工周期短、设计灵活、成形件尺寸精度高、绿色环保等一系列特点。梯度功能材料（FGM）是一种先进的功能性材料，其内部没有明显的界面，材料的成分、组织性能呈梯度变化。在梯度功能材料的制造方法中，激光熔化沉积既可以缓和不同材料间的应力，保证材料优良的成形性，又可以通过灵活的设计来控制成形件组织和性能的变化和分布规律，为梯度功能材料的制造提供了一种新途径。介绍了激光熔化沉积的技术特点、梯度功能材料的特点与应用、国内外激光熔化沉积技术制造梯度功能材料方面的研究进展，以及团队目前在此领域的研究状况，同时分析了利用激光熔化沉积技术制造梯度功能材料的发展前景。

Abstract

Laser melting deposition (LMD) is a typical additive manufacturing technology. Compared to the traditional forming processes

it has a series of features

such as shorter processing cycle

flexible design

higher dimensional accuracy

and environmental protection. Gradient functional material (FGM) is an advanced functional material without obvious interface inside

and the composition and performance graded distribution along thickness. Among the manufacturing method of FGM

LMD not only relieves the stress between different materials

but also ensures the excellent formability of the material

and controls the change and distribution of the microstructure and properties of the formed parts through flexible design. This paper introduces the technical characteristics of LMD

the characteristic and application of FGM

the research progress in manufacturing FGM by LMD at home and abroad

the current research status of team in this field

and the development prospects of the LMD technology for the manufacture of FGM.
