| 摘 要： | 对纳米Y－TZP的浆料进行了凝胶注模成型．有机单体丙烯酸胺和交联剂N，N-亚甲基双丙烯酸胺的加入，不但起到使浆料凝胶的作用，还可以大大降低浆料粘度，改善浆料的流变性．有机单体、交联剂、引发剂均有其合适的用量范围．与干压法、等静压法相比，用凝胶注模法成型的素坯密度高、显微结构均匀、烧结体的断裂韧性也较等静压法高．

| Abstract: | The gelcasting process for shaping nano-sized Y-TZP was studied. The effect of organicmonomer and binder on the rheological properties of slurry was investigated. There existed the optimum amount of monomer, binder and initiator. Compared to dry pressing and isostatic pressingmethods, the specimens formed by gelcasting had higher density, more homogenous microstructureand higher fracture toughness. |
