| 摘 要： | 采用多模微波烧结系统和常压烧结，对Al2O3-ZrO2复合材料的基本性能进行了研究，提出了相关的磨损机理，与常压烧相比，微波烧结可以提高ZTA陶瓷的密度，强度和韧，使其结构均匀，耐磨性提高，常压吉样品的磨损主要是晶粒铲平，磨屑填充体内气孔形成光滑的磨损界面；而向波烧结ZTA陶瓷主要是界面晶粒剥离脱落磨损，载荷的增加使磨损量增大。

| Abstract: | The multi-mode microwave system and conventional sintering were carried out. Properties of Al2O3-ZrO2 composites were investigated, relative wear mechanisms were proposed with regard to the processing approaches. Compared with the conventional results, microwave processed ZTA ceramics appear with the improved relative density, fracture toughness and bending strength, the developed microwave structure, and the ameliorated wear resistance. The wear for the conventional ZTA specimens are mainly caused by the shovel of the interface grains, the porosity is filled by the debris and the smooth wear track is achieved; whereas interface grains in microwave specimens are basically swept out. The incremental loads accelerate the wear. |
