    摘要： The present disclosure provides mechanical attachments of TSD body to a carrier or substrate sufficient to allow eventual conventional attachment of the TSD to a drill bit or other component. According to one aspect, the disclosure includes a composite assembly including a thermally stable diamond (TSD) body and a substrate with aligned holes and a joining pin located in the aligned holes to mechanically attach the TSD body and substrate. The composite assembly may lack any non-mechanical attachment between the TSD body and the substrate, or may lack particular types of non-mechanical attachments. The disclosure also provides drill bits and other devices containing such composite assemblies as well as methods of making such composite assemblies and drill bits or other devices.

    摘要翻译： 本公开提供了TSD主体对载体或基底的机械附接，足以允许最终常规地将TSD附接到钻头或其他部件。 根据一个方面，本公开包括一种复合组件，其包括热稳定金刚石（TSD）主体和具有对准孔的基板和位于对准的孔中的连接销，以机械连接TSD主体和基板。 复合组件可能缺少TSD主体和基板之间的任何非机械连接，或可能缺少特定类型的非机械附件。 本公开还提供了钻头和包含这种复合组件的其它装置以及制造这种复合组件和钻头或其它装置的方法。

    摘要： The disclosure provides a super-abrasive body including a thermally stable polycrystalline diamond (TSP) body having a top region and an enhanced attachment region, wherein the enhanced attachment region includes tungsten carbide particles having a volume of at least 30% of the total volume of the enhanced attachment region. The disclosure further provides a super-abrasive element having the super-abrasive body attached to a substrate via an attachment material located in or around the tungsten carbide particles. The disclosure additionally provides earth-boring drill bits with such a super-abrasive element. Further, the disclosure provides methods of forming such super-abrasive bodies and elements by forming a PCD body with particle of tungsten carbide in an enhanced attachment region, then leaching the PCD body and attaching it to a substrate via an attachment material in or around the tungsten carbide particles.

    摘要： The disclosure provides to a PDC element protective system including a mask configured to protect a non-leached portion of a leached polycrystalline diamond compact (PDC) element during a leaching process. The mask may be formed from or coated with polytetrafluoroethylene (PTFE). The disclosure also provides a leaching system containing such a mask and a leaching vessel as well as methods of using the protective and leaching systems. The disclosure further provides a Lewis acid-based leaching agent and methods of its use. Finally, the disclosure provides a method of recycling a PDC or carbide element using a Lewis acid-based leaching agent.
