METHODS TO REPAIR WORN OR ERODED PDC CUTTERS, CUTTERS SO REPAIRED, AND USE OF REPAIRED PDC CUTTERS IN DRILL BITS OR OTHER TOOLS |
摘要 |
A repaired polycrystalline diamond cutter and method for fabricating the same. The cutter includes a damaged substrate that includes at least one void therein, a polycrystalline diamond table coupled to the damaged substrate, and a paste compound disposed within the voids formed about the damaged substrate. The damaged substrate and the paste compound collectively form a full circumference. The method includes obtaining a damaged cutter that includes a polycrystalline diamond table coupled to a damaged substrate having at least one void formed therein, applying a paste compound within the at least one void, melting the paste compound via induction heating, bonding the paste compound to the substrate and forming a processed PDC cutter, and grinding at least a portion of the paste compound from the processed PDC cutter to form the repaired cutter. |
