| 摘 要： | 对梯度功能陶瓷刀具材料界面裂纹进行了较为详细的研究，提出梯度功能陶瓷刀具材料界面处的裂纹总是复合型的；界面裂纹沿原方向扩展或偏转依赖于原方向和偏转方向的能量释放率之比与相应方向的单位断裂能之比。

| Abstract: | The interface cracks of functionally graded ceramic tool have been studied deeply in this paper. Results show that the interface cracks, which are mixed ones, always propagate in the direction where there is a large surplus of the energy release. |
