Abstract: Embodiments disclosed herein relate to superabrasive compacts, methods of making the same, and drill bits incorporating the same. For example, embodiments of a superabrasive compact disclosed herein (e.g., a PDC) may be formed by providing a superabrasive compact. The superabrasive compact includes a superabrasive body and a cemented carbide substrate bonded to the superabrasive body. The cemented carbide substrate includes a base surface, an interfacial surface bonded to the superabrasive body, and at least one peripheral surface extending between the base surface and the interfacial surface. After providing the superabrasive compact, the method includes lasing at least a portion of the peripheral surface of the cemented carbide substrate to form a corrosion-resistant layer
