    摘要: Cutting elements and bits incorporating such cutting elements are provided. The cutting elements include a substrate having an interface surface over which is formed an ultra hard material layer. A plurality of lands are formed on the interface surface. A plurality of depressions are formed on the lands.

    摘要: Cutting elements and bits incorporating such cutting elements are provided. The cutting elements include a substrate having an interface surface over which is formed an ultra hard material layer. A plurality of lands are formed on the interface surface including a land surrounded by spaced-apart lands extending to a periphery of the substrate.
