Diamond Innovations Inc | Date: 2017-02-15

A superabrasive compact and a method of making the superabrasive compact are disclosed. A superabrasive compact may comprise a superabrasive volume and a substrate. The substrate may be attached to the superabrasive volume via an interface. The superabrasive volume may be formed by a plurality of polycrystalline superabrasive particles. The superabrasive particles may have nano or sub-micron scale surface texture.The surface texture is the result of treating the diamond or cBN particles in hydrogen or oxygen- containing atmoshere. The diamond or cBN particles are joined with the cemented tungsten carbide substrate by high pressure high temperature sintering.

Superabrasive compacts and methods of making superabrasive compacts are disclosed. A superabrasive compact includes a polycrystalline diamond table and a substrate attached to the polycrystalline diamond table. The substrate includes a hard metal carbide and a binder having a compound with a composition of AxByCz, where A and B are transition metals, where C is carbon, and where 0x7, 0y7, x+y=7, and 0z3.


A method for making a polycrystalline diamond compact including the step of providing a polycrystalline diamond compact. The compact has a substrate of a hard metal composition of material and a volume of diamond material disposed on the substrate. The diamond material includes a mixture of diamond particles and a binder-catalyst. At least one pre-coating layer of organic material impermeable to a given acid or mixture of given acids is applied to at least an exterior surface of the substrate. At least one layer of primer material that is impermeable to a given acid or mixture of given acids is applied on the at least one pre-coating layer. A layer of top coating material that is impermeable to the given acid or mixture of given acids is applied to the at least one primer layer. When the given acid or mixture of given acids is applied to the compact to leach the binder-catalyst from the diamond material the at least one pre-coating layer, at least one primer layer and layer of top coating material protect the coated portions of the compact.
