本文对四种PDC片的微观结构进行了对比研究,指出PDC片的金刚石层聚晶不完善是导致其耐磨性能降低的原因。通过对实验结果的分析,还论述了PDC片的磨损机理。
In this paper, we compared the microstructures of the four kinds of PDC sheets, and pointed out that the imperfect polycrystalline diamond sheets in the PDC sheets are the reason for the decrease of wear resistance. Through the analysis of the experimental results, we also discussed the wear mechanism of PDC chip.
