Abstract Scope |
Ultra-high temperature ceramics (UHTC) are of great interest for applications involving extreme environments due to their reliable high temperature structural performance. Ceramic On-Demand Extrusion (CODE) is a direct-write additive manufacturing process which allows for the creation of near theoretically (>99%) dense parts with large cross-sections. Direct-write additive manufacturing processes allow for the integration of sub-structures and graded chemistries. The processing and properties of CODE additively manufactured zirconium diboride (ZrB2) was investigated. Processing optimization including feedstock rheology, pressureless sintering, and print fidelity were explored. Finally, mechanical and thermal properties were also examined and will be discussed. |
