| Abstract Scope |
Cold spray is a widely utilized technology for repairing and producing additive-manufactured components. A key feature of cold spray is its solid-state deposition process, which maintains the original powder microstructure. Due to cold spray being a solid-state technique, the powder quality and resulting depositions are strongly dependent on the powder manufacturing method. In this study, we compared 6061 aluminum powders produced by gas atomization and mechanical milling. These powder processing methods yield powders with distinct microstructures, each of which reacts differently to thermal and mechanical treatments. In-situ micromechanical testing evaluated the deformation behavior of the powder and the cold spray deposition. Additionally, the powders and cold spray depositions' microstructure and micromechanical properties are assessed under the same heat treatment. This study highlights differences in microstructural evolution and micromechanical properties of cold spray deposits from each powder type, emphasizing powder manufacturing routes in optimizing cold spray deposition and advancing the technology. |
