Microstructure and properties of polycrystalline diamond composites for drilling
-
摘要:
采用上层为细粒度金刚石、下层与硬质合金接触的为粗细度金刚石的分层设计理念，制备钻探用多金刚石层的聚晶金刚石复合片（PDC），对比不同粒度的单层金刚石PDC与多层金刚石PDC的显微组织与性能的差异。利用超声波扫描、扫描电子显微镜（SEM）表征每种PDC的内部缺陷和表面形貌等，并分别对PDC的耐热性、抗冲击性和耐磨性进行测试。结果表明：多层金刚石PDC的综合性能良好，其表层耐磨，下层更耐冲击，且其具有更加均衡的耐热性、抗冲击性和耐磨性。细粒度金刚石层PDC的耐磨性更高，但耐热性和抗冲击性较低，而粗粒度金刚石层PDC的耐热性和抗冲击性能更好，但耐磨性较差。
Abstract: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.
