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.

Thick sintered polycrystalline diamond and sintered jewelry

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.

Use of Ti and Nb cemented in TiC in prosthetic joints

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.

Articulating diamond-surfaced spinal implants

Diamond bearings and bearing components are disclosed. Some embodiments of the bearings and bearing components include polycrystalline diamond compacts sintered under high pressure and high temperature to create a diamond table chemically and mechanically bonded to a substrate, the diamond table presenting a durable and thermally stable load bearing and articulation surface.

Bearings, races and components thereof having diamond and other superhard surfaces

Use of Ti and Nb cemented in TiC in prosthetic joints, such as prosthetic joint components made from sintered superhard materials.

Method for making a sintered superhard prosthetic joint component

Carbides as substrates in prosthetic joints, particularly in sintered polycrystalline diamond compacts and sintered cubic boron nitride compacts.

Method of making components for prosthetic joints

Articulating diamond-surfaced spinal implants are disclosed. Materials which may be used to make the spinal implants and manufacturing and finishing techniques for making the implants are also disclosed.

Brut polishing of superhard materials to remove positive asperities by use of pressure and heat.

Brut polishing of superhard materials

CoCrMo can be used to enhance biocompatibility of a sintered polycrystalline diamond compact.

Use of CoCrMo to augment biocompatibility in polycrystalline diamond compacts

Use of gradient layers and stress modifiers in superhard constructs.

Use of gradient layers and stress modifiers to fabricate composite constructs

Various nozzles, components of nozzles, and methods, materials and devices for making them are disclosed.

Nozzles, and components thereof and methods for making the same

Prosthetic joints, components for prosthetic joints, superhard bearing and articulation surfaces, diamond bearing and articulation surfaces, substrate surface topographical features, materials for making joints, bearing and articulation surfaces, and methods for manufacturing and finishing the same, and related information are disclosed, including prosthetic knee joint having at least one diamond articulation surface.
