| Abstract Scope |
This study investigates the feasibility of using a new form of low-pressure cold spray additive manufacturing, termed Brittle Particle Cold Spray (BPCS), for solid-state consolidation of ceramic feedstock powders. Here we investigated process-structure-property relationships of several different BPCS sprayed materials including Boron Carbide, Bismuth Telluride, Neodymium Iron Boride and Ytterbium Monosilicate, among others. Considerations were given to the starting feedstock powder size distribution and shape, as well as to the BPCS deposition efficiency and resulting deposit thickness. Further, the as-deposited materials microstructure, hardness and void content were also characterized. Where appropriate, deposit properties were compared to those of like materials processed by alternative technologies, as reported in the literature. |
