采用闪速烧结法制备了SiC晶须增强ZrO 2复合材料。在最佳工艺条件下制备的复合材料密度接近理论值。SEM观察表明，晶须均匀分布在基体中，并与ZrO 2牢固结合，保持了良好的原始形貌。复合材料的断裂韧性值高于SiC-ZrO 2（与6摩尔%的Y2 O3）由常规热压制成。结果表明，快速烧结法可以更有效地制备SiCw/ZrO 2复合材料。
SiC whisker-reinforced ZrO2composite is prepared by flash sintering. The density of the composite obtained at the optimal conditions is close to the theoretical value. SEM observations reveal that the whiskers with well-preserved original morphology are uniformly distributed within the matrix and strongly bonded with ZrO2. The composite exhibits a fracture toughness value higher than SiC–ZrO2(with 6 mol% Y2O3) made by conventional hot-pressing. These results clearly demonstrate that the flash-sintering can prepare SiCw/ZrO2composites more effectively.
