Selective Laser Sintering in Reactive Atmospheres: Towards In-Situ Synthesis of Net-Shaped Carbide and Nitride Ceramics
2021
Abstract Selective laser reaction sintering techniques (SLRS) were investigated to produce near net-shape non-oxide ceramic materials that were previously incompatible with powder-bed fusion additive manufacturing (AM) methodologies. Specifically, reaction-bonded layers of carbide and nitride materials (Cr3C2 and CrN) were fabricated using SLRS from a model system of Cr and Cr2O3 precursor materials. Varied particle sizes (
