Abstract
Carbides as substrates in prosthetic joints, particularly in sintered polycrystalline diamond compacts and sintered cubic boron nitride compacts.
Claims39
A method for making a component for a prosthetic joint comprising the steps of:
- mixing a carbide selected from the group consisting of Ti and Nb with TiC,
- mixing at least one metal selected from the group consisting of Ti and Nb with said TiC;
- enclosing said mixture of metal and carbide in a niobium can,
- placing said can in a press,
- using said press to form said mixture of metal and carbide into a spherical component by hot isostatic pressing,
- said spherical component being a biocompatible unit for use in a prosthetic joint, said spherical component including a material selected from the group consisting of Ti cemented TiC and Nb cemented TiC.

A method for making a component for a prosthetic joint comprising the steps of:
- mixing a carbide selected from the group consisting of Ti and Nb with TiC to create a feedstock,
- mixing a metal selected from the group consisting of Ti and Nb with said feedstock,
- said mixing being carried out in an attritor mill,
- enclosing said feedstock comprising said carbide and said metal in a niobium can and forming said feedstock into a substantially solid spherical component by pressing,
- said spherical component being a biocompatible unit for use in a prosthetic joint, said spherical component including a material selected from the group consisting of Ti cemented TiC and Nb cemented TiC.
