  • Patent number: 9820539
    Abstract: Methods of forming larger sintered compacts of PCD and other sintered ultrahard materials are disclosed. Improved solvent metal compositions and layering of the un-sintered construct allow for sintering of thicker and larger high quality sintered compacts. Jewelry may also be made from sintered ultrahard materials including diamond, carbides, and boron nitrides. Increased biocompatibility is achieved through use of a sintering metal containing tin. Methods of sintering perform shapes are provided.
    Type: Grant

  • Patent number: 8603181
    Abstract: An improved composition of titanium sintered titanium carbide is provided. The composition provides an improved degree of strength and toughness and improved compatibility with medical imaging. The composition provides good compatibility with sintered polycrystalline diamond, achieving a good mechanical fit in terms of the combined compressibility and thermal expansion during the sintering process to minimize stress or cracking between the substrate and the diamond layer.

  • Patent number: 8016889
    Abstract: Articulating diamond-surfaced spinal implants are disclosed. The implants use sintered polycrystalline articulation surfaces which are attached to spinal endplates and which are implanted to replace damaged spinal joints. The implants provide a long wearing and biocompatible articulation surface. Materials which may be used to make the spinal implants and manufacturing and finishing techniques for making the implants are also disclosed.
