摘要： A PCD structure comprising a first region, in a state of residual compressive stress, and a second region in a state of residual tensile stress adjacent the first region; the first and second regions each formed of respective PCD grades and directly bonded to each other by intergrowth of diamond grains, the PCD grades having transverse rupture strength (TRS) of at least 1,200 MPa. A third region in a state of residual compressive stress may also be provided such that the second region is disposed between the first and third regions and is bonded to the first and third regions by intergrowth of diamond grains.

摘要： A method for making a super-hard construction comprising a first structure comprising a first material joined to a second structure comprising a second material, in which the coefficient of thermal expansion (CTE) and Young's moduli of the materials of each material are substantially different from each other. The method includes forming an assembly comprising the first material, the second material and a binder material arranged to be capable of bonding the first and second materials together, the binder material comprising metal; subjecting the assembly to a sufficiently high temperature for the binder material to be in the liquid state and to a first pressure at which the super-hard material is thermodynamically stable; reducing the pressure to a second pressure at which the super-hard material is thermodynamically stable, the temperature being maintained sufficiently high to maintain the binder material in the liquid state; reducing the temperature to solidify the binder material; and reducing the pressure and the temperature to an ambient condition to provide the super-hard construction.
