In-situ reactive joining of silicon carbide ceramics with zirconium disilicide and graphite
High-strength joining of silicon carbide (SiC) ceramics was achieved at relatively low temperatures through in-situ reaction of zirconium disilicide (ZrSi2) and graphite (C), employed as the joining material. The effects of C content and joining temperature on the microstructure, phase composition, and mechanical properties of the joints were investigated. The interlayer was composed of SiC, zirconium carbide, ZrSi2, and Si-Zr phases. The shear strength of the joint first increased and then decreased with the increase of C content. When the molar ratio of C/ZrSi2 was 2, the shear strength measured of the joint, which was conducted at 1450°C by spark plasma sintering, was 178.2 ± 8.6 MPa. Subsequently, the C/ZrSi2 powder with a molar ratio of 3 was employed to join SiC ceramics at different joining temperatures, and the shear strength of the joint was positively correlated with the joining temperature. The SiC joint achieved in this study offers great potential for application in extreme environments.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
