摘　　要：工程陶瓷机械加工性能差,工程陶瓷表面/亚表面极易产生加工损伤,进而严重影响工程陶瓷零部件的服役性能及疲劳寿命。围绕工程陶瓷磨削加工,从应变率效应和材料本构关系模型等方面阐述了磨削加工损伤的形成及其演变机制;并在此基础上总结了工程陶瓷磨削损伤的影响因素及作用规律;其次,从工程陶瓷低损伤磨削加工工具与加工工艺两个方面深入探讨了抑制工程陶瓷磨削加工损伤的关键技术;最后,展望了抑制工程陶瓷磨削加工损伤关键技术的发展方向。For the poor machining performance of engineering ceramics,the surface/subsurface is prone to processing damage,which significantly impacts the service performance and fatigue life of engineering ceramic parts,the grinding damage formation and evolution mechanism of engineering ceramics are elaborated from the aspects of strain rate effect and material constitutive relation models.Based on this analysis,the influencing factors and the regulation of the grinding damages are analyzed.Then the suppression strategy of grinding damages is investigated in two aspects:grinding tools and processing technology.Finally,a brief outlook on the future development direction of key technologies for grinding damage suppression is presented.
