Abstract A novel method of tape casting to fabricate ceramic-particulate-reinforced composite filler alloy tapes with low organics (no more than 6 wt.%) was developed, with which SiCP/Ag–Cu–Ti hybrid tapes were successfully prepared and used in joining of sintered silicon carbide ceramics. The stress rheometer, scanning electron microscopy and energy dispersive spectrometer were used to characterize the rheological properties of slurry and microstructure of green tapes and joints. The slurry for tape casting consists of dispersant, binder, solvent, a mixture of ceramics particulates and metal powders, and no plasticizer was added. Castor oil phosphate was proven the suitable dispersant for the slurry, and the content of dispersant, binder, solid loading was optimized as 3 wt.%, 2.6 wt.% and 26 vol.%, respectively. The fabricated hybrid tapes possess good ductility and uniform thickness. The SiC particulates were homogeneously distributed in the metal powders matrix in both sides of the green tapes, and the distribution was retained in the SiC/SiC joints.

SiCP/Ag-Cu-Ti杂化带的制备及其在碳化硅陶瓷接合中的应用

摘要 开发了一种新的流延法制备低有机物（不超过 6 wt.%）的陶瓷颗粒增强复合填料合金带，成功制备了 SiCP/Ag-Cu-Ti 杂化带，并将其用于烧结碳化硅陶瓷的接合。采用应力流变仪、扫描电子显微镜和能谱仪对浆料的流变特性以及生带和接缝的微观结构进行表征。流延用浆料由分散剂、粘合剂、溶剂、陶瓷颗粒和金属粉末的混合物组成，不添加增塑剂。蓖麻油磷酸盐被证明是适合浆料的分散剂，分散剂、粘合剂、固体负载的含量分别优化为 3 wt.%、2.6 wt.% 和 26 vol.%。制成的混合带具有良好的延展性和均匀的厚度。SiC 颗粒均匀分布在生带两侧的金属粉末基体中，并且这种分布保留在 SiC/SiC 接头中。
