摘要: An article of jewelry for wearing on the body may comprise a sintered polycrystalline diamond compact with substantially no metal catalyst. As many of the metal catalysts commonly used in the art are known to cause skin irritation, such a sintered compact with substantially no metal catalyst may be more biocompatible than previously known. A method for forming such a biocompatible sintered polycrystalline diamond compact comprises mixing diamond powder and metal catalyst powder into a mixture and sintering the mixture under elevated temperature and pressure conditions to form a sintered compact. The sintered compact may then be leached in an acid or other solution to substantially remove the metal catalyst from the sintered compact.

摘要: In one aspect of the present invention, a pick assembly is configured that comprises a pick shank configured to be press fit directly within a bore of a block. The pick shank comprises an inside and outside surface. The pick comprises a pick head opposite the shank. The shank comprises at least one longitudinal recess extending towards the pick head along the shank from a distal end of the shank. The recess allows the shank to resiliently collapse upon insertion into the bore while maintaining a press fit between the bore and the shank.
