摘要

采用水带铸造技术制备了用于电解质支撑固体氧化物燃料电池(SOFC)的氧化钇稳定氧化锆薄膜。胶带浇注浆料的粘结剂含量在20%至25%之间变化。一种用作粘合剂的商用丙烯酸乳液。对两种浆料进行了流变学测量。两种浆料均表现出剪切减薄行为。含有25%黏合剂的胶带具有足够的柔韧性和光滑均匀的表面，没有裂缝和其他缺陷。找到了合适的层合条件，层合板的理论密度达到54%。与单层胶带相比，层压胶带具有更高的抗拉强度。胶带取向对其力学性能有显著影响。抗拉强度、应变伸长率和杨氏模量在铸态方向上测得较高的性能值。

Mechanical Behavior of Yttria-Stabilized Zirconia Aqueous Cast Tapes and Laminates

Aqueous tape casting was used to produce yttria-stabilized zirconia films for electrolyte-supported solid oxide fuel cell (SOFC). Tape casting slurries were prepared varying the binder content between 20 and 25 wt%. A commercial acrylic emulsion served as binder. Rheological measurements of the two slurries were performed. Both slurries showed a shear-thinning behavior. Tapes with 25 wt% binder exhibited adequate flexibility and a smooth and homogeneous surface, free of cracks and other defects. Suitable conditions of lamination were found and a theoretical density of 54% in the laminates was achieved. Laminated tapes showed higher tensile strength compared to single sheets. Tape orientation has a significant influence on the mechanical properties. Tensile strength, elongation to strain, and Young’s modulus measured in samples produced in the direction of casting showed higher property values.
