In this research, we focus on the parameters optimization for powder manufacturing using rePowder atomization of various Mg-based powders for further sintering using Laser Powder Bed Fusion (LPBF) techniques. The cast rods of ZX00, ZX50, and ZX50 with Ag addition were atomized via ultrasonic atomization using a rePowder device (AMAZEMET, Poland). The alloy was melted in a graphite crucible with a 400 cm³ volume at a heating rate of 150 K/min up to 1023 K and kept for 2 min at this temperature under an Ar atmosphere with oxygen content below 40 ppm as firstly chamber was evacuated using vaccum pump. Subsequently, the molten alloy was poured using pressure differential pressure through nozzle with 1,2 mm orfice diameter on a plate-type sonotrode, which vibrated at 40 kHz frequency. As a result of a atomization process, the powder with high sphericity was produced. The particle size distribution of as-atomized powders is suitable for alloy development for additive manufacturing as most of the particles were below 100 microns. The powder was collected under an inert atmosphere and sieved to obtain particles with the desired size. [ABSTRACT FROM AUTHOR] |
