摘要
激光选区熔化技术是金属增材制造的主流技术之一,AlSi10Mg 具有强度高、力学性能好等优点,广泛应用于汽车零部件、航空航天等行业,在部分轻型零件中可替代高成本的钛合金.在成型基板上不同位置设计 9 个方形结构试块,采用 80μm大层厚,研究激光功率、扫描间距、扫描速度三个工艺参数对制件致密度的影响规律与主次顺序,研究结果可为工业生产中 AlSi10Mg的应用与推广提供理论基础和实验依据.
Abstract
Selective laser melting technology is one of the mainstream technologies in metal additive manufacturing.AlSi10Mg has advantages such as high strength and good mechanical properties,and is widely used in automotive parts,aerospace and other industries.In some lightweight parts,it can replace high-cost titanium alloys.Design 9 square structural test blocks at different positions on the formed substrate,and a large layer thickness of 80μm is adopted to study the influence of three process parameters,namely laser power,contour spacing,and scanning speed on the density of the workpiece,as well as the primary and secondary order,can provide a theoretical basis and experimental basis for the application and promotion of AlSi10Mg in industrial production.
