摘　　要：聚晶金刚石复合片是采用HPHT方法生产的,所以不可避免地在界面处、以及聚晶金刚石层内部的缺陷处存在大量的残余应力。本文主要围绕聚晶金刚石复合片的应力表征问题进行了实验和理论分析。实验、研究表明,聚晶金刚石复合片在聚晶金刚石层内存在着宏观应力和微观应力,即第一类内应力、第二类内应力;聚晶金刚石表面应力的大小可以反映聚晶金刚石层的应力存在状况;XRD方法可以用于聚晶金刚石复合片应力的表征。PDC（ polycrystalline diamond compact） is produced by the method of HPHT（ high pressure and high temperature）, it unavoidably exists some residual stress at the interface and in the layer of PDC. In this paper studies were made on the stress characterization of PDC by tests and analysis on the theory, and these results showed that in the layer of PDC it exists maerostress and microstress, namely, the first class and the second class internal stress. The surface stress of PDC can reflect the state of the layer and XRD method also can be used for the stress characterization of PDC.
