摘要 采用超重力下燃烧合成技术,以快速凝固方式制备了Al2O3/ZrO2(4Y)复合陶瓷,用XRD、SEM与EDS等研究了ZrO2含量对复合陶瓷显微结构和性能的影响。结果表明:当复合陶瓷中ZrO2质量分数在34.1%~46.4%时,复合陶瓷的显微结构主要为棒晶;当质量分数为49.6%~53.7%时,其显微结构主要为形状不规则的ZrO2球晶;随着ZrO2含量的增加,复合陶瓷的相对密度逐渐降低(最高可达94.3%),而硬度和断裂韧度均呈先增高后降低的趋势,当ZrO2质量分数为42.6%时,硬度和断裂韧度均达到最高值,分别为13.1GPa和13.5MPa·m^1/2。 Based on combustion synthesis technology under high gravity to prepare rapidly solidified composite ceramic Al2O3/ZrO2(4Y), the influence of ZrO2 content on microstructure and properties of solidified composite ceramics Al2O3/ZrO2(4Y) was investigated through XRD, SEM and EDS. The results show that the main microstructure of the ceramic was rod-shaped eutectic colonies as the ZrO2 content was in the range of 34.1% --46. 4 %, and the microstructure transformed to be isolated spherically-shaped ZrO2 grains as the ZrO2 content was in the range of 49.6%- 53. 7%. With the ZrO2 content increasing, the relative density of the ceramic decreased, the maximum value was 94. 3%, whereas the hardness and the fracture toughness increased first and then decreased. The maximum hardness value of the composite ceramic reached 13. 1 GPa as the ZrO2 content was 42. 6%, and the maximum fracture toughness value of 13. 5 MPa · m^1/2 was also obtained.
