| Abstract Scope |
As additive manufacturing (AM) technologies continue to develop towards more sustainable and energy efficient methodologies, there is a need for reducing the overall carbon footprint of the entire supply chain, specifically with feedstock powders. Typically, atomized powder undergoes several extraction and remelting steps before its end use in AM applications. However, there is an opportunity to utilize powders directly after the Hunter extractive metallurgical process to reduce energy costs. This work will discuss the characterization of commercially pure (Grade 2) titanium sponge particles directly after the Hunter process for the eventual use in cold spray AM (CSAM). CSAM has several advantages: low thermal impact on the substrate, no melting of the feedstock material, and compressive residual stresses within the final part. In this study, powder characterization includes shape, porosity, and microstructure measurements using a combination of techniques involving micro X-ray computed tomography and scanning electron microscopy. |
