摘　　要：目的研究不同基体烧结温度对氧化铝-氧化锆纳米复合渗透陶瓷力学性能的影响。方法采用不同的基体烧结温度制备氧化铝-氧化锆纳米复合渗透陶瓷,测试其抗弯强度和断裂韧性;扫描电镜观察其显微结构。结果基体烧结温度采用1 2501、3001、350℃所得复合渗透陶瓷的3点弯曲强度和断裂韧性测试结果差异无统计学意义。结论在不同基体烧结温度下,氧化铝-氧化锆纳米复合渗透陶瓷都表现出良好的力学性能。Objective To give a basic understanding of the influence of different matrix sintering temperature to the mechanical properties of alumina-zirconia nano-composite infiltrated ceramic.Methods To process the alumina-zirconia nano-composite infiltrated ceramic by 1 250,1 300 and 1 350 matrix sintering temperature.The consequent data were analyzed with one way ANOVA.Results The mechanics test results of the composite infiltrated ceramic sintered by 1 250,1 300 and 1 350 matrix sintering temperature had no statistical differences.Conclusion The test result shows this kind of material has good mechanical property.
