| 为了满足结构件的一体式、轻量级以及专属定制的要求，笔者对激光熔化沉积（laser metal deposition，LMD）成形Al 12Si合金激光工艺参数进行了摸索，优化激光成形参数；在此基础之上，开展激光熔化沉积成形实验，通过金相分析、扫描电子显微镜（scanning electron microscope，SEM）等表征手段对激光熔化沉积制备Al 12Si合金显微组织进行表征。结果表明：在激光功率700~800 W、激光扫描速度为300~360 mm/min的工艺参数下能够获得高度致密的Al 12Si合金。激光熔化沉积Al 12Si合金成形工艺的研究旨在克服传统制造方式的局限性，通过科学的方法优化工艺参数并改善成形质量，最终获得高质量且性能优异的Al 12Si合金部件。 |

| In order to meet the requirements of one piece, lightweight and exclusive customization of structural parts, the laser process parameters of LMD（laser metal deposition） forming of Al 12Si alloy were explored and optimized. On this basis, the experiments of LMD forming were carried out, and the microstructures of Al 12Si alloy prepared by LMD were characterized by metallographic analysis and scanning electron microscope(SEM). The results show that highly dense Al 12Si alloys can be obtained under the laser forming process parameters of 700-800 W laser power and 300-360 mm/min laser scanning speed. The research on the forming process of Al 12Si alloy by laser melting deposition aims to overcome the limitations of the traditional manufacturing methods, optimize the process parameters and improve the forming quality through scientific methods, and ultimately obtain high quality and excellent properties of Al 12Si alloy parts. |
