| Abstract Scope |
In Cold Spray Additive Manufacturing, soft metal powders such as aluminum and copper exhibit a high material efficiency, successfully depositing nearly 100% of consumed powder. However, for metal powders with higher hardness and/or low ductile-brittle transition temperatures, the cold spray process may deposit a small fraction of the used powder, the rest lost as it rebounds off the work surface. In order to reduce costly material losses, this work recovers and characterizes two high-cost refractory alloy powders used in cold spray, then processes these recovered powders to regain near-original powder properties. The powders are examined for changes in chemical composition, size distribution and morphology, as well as mechanical testing such as nanoindentation and micro compression to determine its viability for re-use in further cold spray processing. |
