摘要： PCD inserts comprise a PCD body having multiple FG-PCD regions with decreasing diamond content moving from a body outer surface to a metallic substrate. The diamond content changes in gradient fashion by changing metal binder content. A region adjacent the outer surface comprises 5 to 20 percent by weight metal binder, and a region remote from the surface comprises 15 to 40 percent by weight metal binder. One or more transition regions are interposed between the PCD body and substrate. The transition region comprises PCD, binder metal, and a carbide, comprises a metal binder content less than that present in the PCD body region positioned next to it.

摘要： A method of characterizing a quality of a polycrystalline diamond compact (PDC) cutter includes obtaining a PDC cutter that includes a leached layer and an unleached layer. The unleached layer is positioned adjacent to the leached layer, and the leached layer has at least a portion of a catalyst material removed from therein. The method further includes measuring capacitance values of the PDC cutter at multiple frequencies of an electrical signal provided to the PDC cutter by a capacitance measuring device to measure the capacitance values of the PDC cutter. The method also includes characterizing a quality of the PDC cutter based on a lowest capacitance value from among the capacitance values. Each capacitance value of the capacitance values is measured at a respective frequency of the multiple frequencies of the electrical signal.
