| Abstract Scope |
Electrophoretic deposition (EPD) is a colloidal processing method in which an applied electric field is used to deposit particles out of a fluid suspension. Despite EPD’s long tenure for forming near-net shape ceramic green bodies, the technique is largely unexplored for ultra-high temperature ceramics (UHTC) and ceramic matrix composites (UHTCMCs). UHTCMCs are being considered for extreme environment applications due to their desirable material properties; the matrix phase offers thermochemical protection at temperatures exceeding 2000 °C, while the reinforcement phase provides enhanced mechanical toughness to inhibit brittle failure. EPD is attractive for its potential to be a low-cost, high-throughput solution to UHTCMC processing, compared to conventional approaches with lengthy processing cycles. This work illustrates the feasibility of EPD by co-depositing ZrC and SiC on 2D carbon fiber preforms, demonstrating high fidelity in controlling the deposition rates and the fiber-to-matrix ratio in the fabricated green bodies. |
