Abstract

The metal-organic chemical vapor deposition (MOCVD) conducted in fluidized bed was employed for the preparation of nano-sized ceramic-matrix composites. The metal-organic source was vaporized and then deposited onto ceramic-matrix powder surface. The composite powders were reduced in a gas mixture of H ₂/N₂, and then sintered. In this study, two kinds of composites, Mo₅Si₃/Si₃N₄ and Cr ₃C₂/Al₂O₃ were investigated. The XRD, SEM, and TEM were used to characterize the microstructure of samples at different processing stages. The mechanical properties of the composites were studied, too. Preliminary results indicate that the morphology of the initial deposition phase is amorphous with individual or island-like. Results also indicated that the mechanical properties of the sintered composite (only Mo ₅Si₃/Si₃N₄ was presented) was improved by the incorporation of nano second phase.
