Study on the Forming Quality and Microstructure of ZL205A Aluminum Alloy by Selective Laser Melting Forming
This study prepared ZL205A aluminum alloy powder using atomization technology,and prepared ZL205A aluminum alloy using Selective Laser Melting(SLM)technology.The effect of laser energy density on the forming quality of ZL205A alu-minum alloy formed by SLM was analyzed.Study the effect of laser energy density on the density and microstructure of ZL205A sample,with laser power and scanning speed as the main influencing factors.The results showed that when the laser power was 340 W and the scanning speed was 1600 mm/s,the formed sample had the highest density,no obvious cracks,only a small amount of porosity defects,and the density reached 95.996%.
