Abstract:
The introduction of additive manufacturing in the production of advanced parts for aerospace and similar high-end applications have increased the demands on the powder. To ensure future powder availability for additive manufacturing market, Höganäs has invested in new VIGA atomizer. In this report some of the experience of qualification of AM powders to new modern atomization line are outlined. The new system is easier to operate which should translate into less downtime. Due to improved gas flow in the atomizing tower the new system should improve particle morphology and exhibit less variation in physical properties of the powder. For this reason, physical and chemical properties of the powder were systematically measured in order to compare performance to the older atomizer. Furthermore, a number of prints using the LPBF process were performed, and the mechanical properties of the printed and heat-treated parts were compared.
