摘　　要：本文应用X射线衍射法就几种常用结构陶瓷磨削表面残余应力的形成机理、状态特征及与磨削用量的关系进行实验研究。结果表明：磨削表面的残余应力由毛坯表面层原始应力σ0和磨削残余应力Δσ面。两部分组成。σ0受陶瓷材料、毛坯形状及烧结工艺的影响有较大的变化。Δσ的大小及拉压特性取决于陶瓷的磨削过程特征和磨削温度。The formation and characteristics of residual stress are investigated by the grinding and XRD test of structure ceramics ZrO2 .Si3N4 .Al2O3. It is showed that: residual stress of ground surface conisists of original stress of sample σ0 and grinding residual stress Δσ. Ceramic properties, geometric shape and sintering process have important influence on σ0 The magnitude and tension or compression state of ad depend on the grinding feature and temperature dominated by grinding conditions.
