Magnetron sputtering has emerged as a promising and versatile deposition method for coating nano- and micro-lattices to produce novel core-shell composite structures. By leveraging sputtering’s expansive material workspace and its ability to tailor coating microstructure, this work aims to achieve unrealized combinations of lattice geometry, composition, microstructure, and feature size to further functionalize these advanced hierarchical materials. Previous work has demonstrated that sputtering can effectively introduce new ceramic, metallic, and alloyed materials onto lattice structures; however, coating gradients and morphological variations have also been observed. This research seeks to further develop core-shell composite nano- and micro-lattices by examining the influence of sputtering parameters, cathode geometry, and deposition line-of-sight on the resulting coating characteristics on these complex 3D structures. Creating a foundational understanding of sputter deposition on nano- and micro-lattice materials will enable more accurate design and synthesis of novel architected core-shell composites.
