摘要
A cutting element and a method of providing the cutting element are provided. The cutting element may include a substrate, a first polycrystalline diamond zone, and a second polycrystalline diamond zone. The first polycrystalline diamond zone may be substantially free of a catalyst material. The second polycrystalline diamond zone rich in the catalyst material may be bonded to the substrate along an interface. The second polycrystalline diamond zone may be bonded to the first polycrystalline diamond zone along an effective transition zone. The effective transition zone may have a plurality of irregular projections toward the first polycrystalline diamond zone and the second polycrystalline diamond zone.
