titleOfInvention | Pocketed stud for polycrystalline diamond cutting blanks |
abstract | POCKETED STUD FOR POLYCRYSTALLlNE DIAMOND CUTTING BLANKS ABSTRACT OF THE DISCLOSURE Disclosed is an improved brazed implement comprising a composite compact having an abrasive particle layer bonded to a support and a substrate bonded to the support by a brazing filler metal having a liquidus substantially above 700°C disposed therebetween. In a preferred embodiment the composite compact comprises a sectioned cylindrical composite compact having a lower support surface opposite the support surface bonded to said abrasive particle layer. The composite compact also has a mating surface. The substrate about its upper end has a pocket which comprises an interior face complementary in shape with the compact lower support surface and a land complementary in shape with the compact mating surface. The compact is brazed to the substrate. The abrasive particle layer is spaced-apart from contact with the substrate a distance adequate to minimize thermal damage thereto during the brazing of the compact to the substrate. The land is of sufficient depth, however, to provide support for the compact. The preferred composite compact comprises a polycrystalline diamond compact bonded to a cemented carbide support. The preferred substrate is a cemented carbide substrate. The improved implement has special utility in drill bits for oil and gas exploration and in mining applications. |
