| Abstract Scope |
Deformation- and impact-based consolidation of hard particles is desirable for advanced materials processing but remains challenging due to the limited plasticity of hard powder particles. One promising strategy to address this challenge is to coat hard particles with a softer metallic shell, forming core–shell structures that facilitate deformability. In this work, we systematically investigate the processing science of core–shell particles fabricated via electrodeposition. Specifically, we developed an intermittent electro-deposition approach to synthesize copper-coated tungsten core–shell particles tailored for deformation-based applications. A comprehensive processing map was established by systematically varying key deposition parameters, including rotation speed, current density, and deposition time. The resulting core–shell particles were characterized using scanning electron microscopy and X-ray microcomputed tomography to inform coating uniformity and structural integrity, and to identify optimal processing conditions. Additionally, potential defects arising from suboptimal deposition parameters and their underlying mechanisms were analyzed and will be discussed. |
