摘要： Polycrystalline diamond (PCD) constructions and cutting elements include a PCD body having a composite layer with a number of PCD particles dispersed in a surrounding PCD matrix. The composite layer has a wear surface including asperities projecting outwardly therefrom, where the asperities are formed from the PCD particles. In an embodiment, the asperities enhance the efficiency of breaking rock during a drilling operation. The body includes one or more PCD transition layers between the composite layer and a metallic substrate attached to the diamond-bonded body. The one or more transition layers may have a hardness that is the same or less than the hardness of the composite layer.
