Abstract Scope |
Efficient fabrication of high-quality copper parts, especially for components with complex geometries, could be accomplished by Additive Manufacturing (AM) processes, such as the Electron Beam Powder Bed Fusion (EB-PBF). The feedstock material to the EB-PBF process is in powder form with specific characteristics, one of which is powder flowability, which influences the quality of final fabricated products. Powder flowability strongly depends on the geometry of powder particles. It has been well-documented that spherical geometries result in better powder flowability. In this study, the copper powder was spheroidized using an induction plasma spheroidization process. The resulted powder (spheroidized) was compared to the as-received powder in terms of morphology and powder flowability to elucidate the impact of the plasma spheroidization process on powder characteristics. The morphology of both as-received and spheroidized powders was characterized by measuring particle size and shape distribution. The Revolution Powder Analyzer was used to quantify the powder flowability. |
