| Abstract Scope |
Spherical powders of Ti64 alloy dedicated for Additive Manufacturing are currently manufactured mainly by gas or plasma atomization method. Such processes produce a significant amount of powder grains with a diameter too large for the intended use.
As part of the research, the oversized powder was subjected to hydrogenation, grinding, sieving, dehydrogenation and plasma spheroidization. The HDH process sequence tested on a laboratory scale with samples weighing tens of grams showed very promising results.
When scaling the process up to several thousand grams batch size, difficulties were encountered related to powder oxidation and incomplete dehydrogenation.
A mass spectrometer coupled with a furnace was used to analyze the course of thermal processes on a larger scale, which allowed for the identification of some causes and possible solutions. |
