摘要
对金刚石-硬质合金超高压烧结系统合成的PDC复合材料,采用SEM、EDS、BEI和XRD等方法,分析了YG20硬质合金中粘结相钴在PCD层中的扩散特性及作用机制,探讨了钴熔体扫越式催化再结晶扩散渗透对烧结体性能的影响。
The diffusion characteristics and action mechanism of the cementation phase cobalt in YG20 hard alloy in polycrystalline diamond （PCD）layer were analyzed using scanning electron microscope （SEM）, ener- gy dispersive spectrometer （EDS）, backscattered electron image （BEI）, X-ray diffraction （XRD） for PDC that was synthesized in ultra-high pressure sintering system. The influence of the diffusion and permeation of cobalt melt catalysis recrystallization on the performance of the sintering body was discussed.
