Particle Design via Wet Powder Integration Process for Structural Control of Sintered Artifacts

In manufacturing of advanced functional materials, nanoadditives are often used to induced desired functionalities using powder metallurgy method. Although a vast nanoadditives are available, maximization of their full potential is hindered by the inability to control their distribution within a composite matrix. Therefore, there is a need to control the distribution of nanoadditives incorporation, which is feasible using a wet powder integration process via the electrostatic assembly (EA) method. A brief overview of the EA method is provided along with its feasibility in composite particles and granules design are demonstrated. A controlled powder integration using this method could be beneficial toward the fabrication of multiscale advanced composites using a scalable powder-metallurgy-inspired route.
