| Abstract Scope |
The automobile and aircraft industry needs to reduce emissions and resources because they cause multiple impacts on the environment. These industries have focused on developing new manufacturing techniques such as additive manufacturing, particularly atmospheric pressure plasma deposition (APPD), a technology used in the manufacture of advanced multifunctional composite materials. We have developed metallic matrix composites (MMCs) in the form of pellets, using micron powders as precursors; Al and Cu particles act as the metallic matrix, and uncoated powders of Mo and with a Cu coating of approximately 300nm thickness act as fillers. Cu coatings were made via physical vapor deposition. Different parameters of the resulting samples were characterized, such as density, crystalline structure, microstructure and compositional analysis, and thermal properties. These results show a reduction in thermal energy storage (heat capacity) and an improvement in heat transfer (thermal conductivity), making these printable materials suitable for heat sink applications. |
