    Abstract: PCD materials comprise a diamond body having bonded diamond crystals and interstitial regions disposed among the crystals. The diamond body is formed from diamond grains and a catalyst material at high pressure/high temperature conditions. The diamond grains have an average particle size of about 0.03 mm or greater. At least a portion of the diamond body has a high diamond volume content of greater than about 93 percent by volume. The entire diamond body can comprise high volume content diamond or a region of the diamond body can comprise the high volume content diamond. The diamond body includes a working surface, a first region substantially free of the catalyst material, and a second region that includes the catalyst material. At least a portion of the first region extends from the working surface to depth of from about 0.01 to about 0.1 mm.

    Abstract: A press, an automated loading system for a press and related methods are provided including a loading system having a first assembly configured to carry a reaction cell to an anvil of a press base and a second assembly configured to assist in positioning and orientating the reaction cell on the anvil. In one embodiment, the first assembly may include a trolley displaceable along a guide member to carry the reaction cell to the anvil. The first and second assemblies may each include guide members that are displaceable relative to the anvil that are configured to position the reaction cell at a desired location and orientation on the anvil. In one embodiment, each of the guide members include arms that engage distinct sides of a cubic reaction cell. A clearing mechanism may also be incorporated to clear the surface of the anvil during operation of the system.

    Abstract: Methods for removing, or leaching, cobalt or other diamond-diamond bonding catalysts from polycrystalline diamond compacts (PDCs) or other structures formed from polycrystalline diamond include leaching under conditions that simulate use of PDCs in a hot hole drilling environment. A leaching agent may be formulated, when used under appropriate conditions, to remove or substantially remove cobalt or another catalyst from polycrystalline diamond without dissolving, degrading or otherwise attacking a substrate that supports or carries the polycrystalline diamond. The leaching agent may include one or more components that mimick the chemicals or conditions to which a PDC would be exposed in a hot hole drilling environment. Polycrystalline diamond structures from which cobalt or another diamond-diamond bonding catalyst has been removed or substantially removed are also disclosed, as are systems for leaching cobalt or other diamond-diamond bonding catalysts from polycrystalline diamond.
