    摘要: In one aspect of the invention, a method of forming polycrystalline diamond comprises providing a can assembly comprising a preform of diamond powder with a first catalyst, the preform being adjacent a solid substrate with a second catalyst. The pressure and/or temperature on the can assembly increases until the first catalyst and carbon from the diamond powder begin to form a melting composition within the preform. The pressure and temperature may be held substantially constant on the can assembly until the melting composition has catalyzed crystalline growth in at least a portion of the preform. The pressure and/or temperature are then increased on the assembly until the second catalyst within the substrate is released into the preform.

    摘要: In one aspect of the invention, a tool has a working portion with at least one impact tip brazed to a carbide extension. The carbide extension has a cavity formed in a base end and is adapted to interlock with a shank assembly of the cutting element assembly. The shank assembly has a locking mechanism adapted to interlock a first end of the shank assembly within the cavity. The locking mechanism has a radially extending catch formed in the first end of the shank assembly. The shank assembly has an outer surface at a second end of the shank assembly adapted to be press-fitted within a recess of a driving mechanism. The outer surface of the shank assembly has a coefficient of thermal expansion of 110 percent or more than a coefficient of thermal expansion of a material of the driving mechanism.
