摘要
Abstract
Residual stress is widely spread in polycrystalline diamond compact PDC products which leads to failure PDC In this research we studied the composition of residual stress and established an inspection method to analyze residual stress by using XRD The distribution rule of the stress is also discussed The influence of thickness of PCD layer size of diamond particle shape of interface and content of Co on PDC residual stress is studied to provide a reference for residual stress control In conclusion it is showed that 1 on the surface of diamond layer the maximum appears in the centre and decreases along radial direction 2 the stress near the interface between PCD layer and carbide matrix has significant influence on service character of PDC product.关键词
