摘要:
The invention relates to polycrystalline diamond compacts ("PDCs") including a polycrystalline diamond ("PCD") table (114) in which cobalt, iron or nickel is alloyed with phosphorous to improve the thermal stability of the PCD table. The PDC includes a substrate (107) and a PCD table(114) including an upper surface (112) spaced from an interfacial surface (103/106) that is bonded to the substrate (107). The PCD table includes a plurality of diamond grains defining a plurality of interstitial regions. TThe alloy is disposed in at least a portion of the plurality of interstitial regions. The alloy contains at least 80 weight% of an intermetallic compound of Co/Ni/Fe and P.
摘要(中):
本发明涉及包括多晶金刚石(“PCD”)台(114)的多晶金刚石压块(“PDC”),其中钴,铁或镍与磷合金以提高PCD表的热稳定性。 PDC包括衬底(107)和PCD台(114),其包括与接合到衬底(107)的界面(103/106)间隔开的上表面(112)。 PCD表包括限定多个间隙区域的多个金刚石晶粒。 T合金设置在多个间隙区域的至少一部分中。 该合金含有至少80重量%的Co / Ni / Fe和P的金属间化合物。
