MECHANICAL ATTACHMENT OF THERMALLY STABLE DIAMOND TO A SUBSTRATE |
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. |
