摘要
激光增材制造技术主要分为选区激光熔化和激光直接沉积,其能够满足个性化需求,制造复杂构件时具有无可比拟的优势。简要介绍了激光增材制造技术的原理与方法,通过对国内外有关文献进行调研与分析,阐述了目前激光增材制造构件的残余应力、裂纹、球化和孔隙等内在缺陷所对应的处理方法和工艺,并提出了解决激光增材制造产品缺陷的方法。
Abstract
Laser additive manufacturing is mainly divided into selective laser melting and laser direct deposition, which can meet the individual needs and has unparalleled advantages in the manufacturing of complex components. The principle and methods of the laser additive manufacturing technology are briefly introduced. Through the investigation and analysis of relevant literatures at home and abroad, the treatment methods and processes corresponding to the internal defects such as residual stresses, cracks, spheroidization and pores of laser additive manufactured components are described. A method for solving defects in laser additive manufactured products is proposed.
