| description | Using the layered design concept of fine-grained diamond in the upper layer and the coarse-fine diamond in contact with the cemented carbide layer in the lower layer, the polycrystalline diamond compact (PDC) with multiple diamond layers for drilling was prepared. The differences in microstructure and performance between the single-layer diamond PDC and the multi-layer diamond PDC with different particle sizes were compared. The internal defects and surface morphology of the PDC were characterized using ultrasonic scanning and scanning electron microscopy (SEM), and the heat resistance, impact resistance and wear resistance of the PDC were tested, respectively. The results show that the comprehensive performance of the multi-layer diamond PDC is good. The surface layer is wear-resistant, while the lower layer is more impact-resistant. The PDC exhibits a more balanced combination of heat resistance, impact resistance and wear resistance. Specifically, the fine-grained diamond layer PDC demonstrates higher wear resistance but lower heat and impact resistance; while the coarse-grained diamond layer PDC exhibits better heat and impact resistance, but poor wear resistance. |
