Abstract Laser powder bed fusion (L-PBF) exhibits many technological opportunities for producing high-performance metallic parts with tailored architectures. However, fabrication of suitable composite powders possessing good flowability, controllable particle size and distribution is a currently prerequisite and main challenge. In this work, two novel techniques, namely freeze-dry pulsated orifice ejection method (FD-POEM) [1] and ultrafine bubble (UFB)-assisted heteroagglomeration [2], have been developed to fabricate uniform composite powders. By taking MoSiBTiC alloy powders as an example, the working principle of FD-POEM process was firstly illustrated. The spherical FD-POEM particles were consisted of typical mesh structures induced by… More >
