摘　　要：针对目前氮化硅陶瓷球材料性能评价体系不完善,以及各个厂家生产的陶瓷球质量参差不齐的问题,对3个较著名厂家(记为A、B、C)的陶瓷球的密度、显气孔率、硬度、断裂韧性及压碎载荷等主要性能参数进行了研究,对陶瓷球各性能参数之间的内在联系进行了相关性分析,建立了一种包含上述主要材料性能参数评价指标的评价体系,利用精密天平、硬度测量仪及万能试验机对上述材料性能参数进行了测试。研究结果表明,综合运用以上评价指标可以实现对陶瓷球材料性能的全面测评,B厂生产的陶瓷球综合性能较高,C厂家球体因压碎载荷值偏低而未达到性能评价标准;球体性能参数内在联系表现为断裂韧性与硬度相关性最大且为负相关,压碎载荷与显气孔率相关性最大。Aiming at the problems of imperfect material performance evaluation system of silicon nitride ceramic ball and uneven quality of ceramic balls from different manufacturers,the test of main performance parameter of ceramic balls from three different manufacturers（ A,B,C）,which contained the density,porosity,hardness,fracture toughness and crushing load was researched. The inherent relationship between various performance parameters of ceramic ball was analyzed by correlation analysis. An evaluation system which contained above-mentioned performance parameters was established. Precision balance,hardness measuring instrument and universal testing machine were used to measure. The results indicate that the materials properties of ceramic ball can be comprehensive evaluated by the above evaluation system,the comprehensive performance of ceramic ball from B manufacturer is better,and the balls from C manufacturer cannot reach the evaluation standard for crushing load value is generally low,the correlation between fracture toughness and hardness is the maximum with negative correlation,and the correlation between crushing load and porosity is the maximum.
