Abstract Scope |
Deposition of metal powders through Cold Spray Additive Manufacturing exhibits a wide range of material efficiency. For softer metal powders such as aluminum, nearly 100% of consumed powder can be successfully deposited on the work surface. However, for harder metal powders such as titanium, the cold spray process may deposit less than half of the powder consumed by the system, with the remaining powder lost as it rebounds off the work surface. To recycle the un-deposited powder particles for re-use, and reduce costly losses, this work fitted a cold spray booth with an intermediary powder collection system. Titanium powder was recovered and characterized using scanning electron microscopy, chemical composition analysis, powder size, shape, and moisture analysis, and mechanical performance testing including nanoindentation and micro compression. The recovered powder was compared to raw feedstock powder to determine its viability for re-use in further cold spray processing. |
