    Description

    This study employs Direct Ink Writing (DIW) 3D printing technology to fabricate ceramic matrix composites (CMCs) with complex geometric structures, enabling the production of components with intricate designs that are challenging to achieve through conventional methods. The incorporation of nickel (Ni) powder as a reinforcement phase enhances the rheological properties of the slurry during the preparation process, ensuring printability and structural integrity. The resulting CMCs exhibit improved mechanical properties, including higher strength and toughness, compared to unreinforced ceramics. These enhancements are likely attributed to the melting of Ni during sintering and its subsequent reaction with silicon carbide (SiC), forming a robust interfacial bonding network. This work aligns with recent advancements in additive manufacturing of CMCs, offering insights into optimizing slurry formulations and sintering mechanisms for high-performance applications.
