| 摘 要： | 利用X-射线衍射方法测量了经不同磨削的氮化硅陶瓷表面残余应力及其对抗弯强度的影响。结果表明,磨削工艺所引入的残余应力是拉应力,对陶瓷抗弯强度有显著降低。

| Abstract: | The residual stresses on the surface of the differently ground and polished silicon nitride ceramics were measured using X ray diffraction method.The effect of the residual stress on the bending strength was investigated.As a result,in this study,the residual stresses introduced by grinding process were tensile and had a significant effect on reducing the bending strength. |
