Abstract: A method of rough shaping a prosthetic joint component that includes a generally spherical polycrystalline diamond compact by electric discharge machining is disclosed. The discharge machining electrode roughens a polycrystalline diamond compact sphere while the electrode and the sphere are rotating about different axes. By controlling the amount of discharge current, the depth and amount of the heat affected zone can be minimized. In the case of a polycrystalline diamond compact, the heat affected zone can be kept to about 3 to 5 microns in depth and is easily removable by grinding and polishing.

Abstract: A prosthetic joint with polycrystalline diamond compact coated interfaces and a method for making the same are disclosed. The prosthetic joint has a diamond layer formed on at least one of the interacting, load-bearing surfaces of the joint. The diamond layer adds resistance to damage from impacts and, when polished, gives the joint a low coefficient of friction, thereby increasing the life of the joint. In accordance with one aspect of the invention, the diamond layer is formed of polycrystalline diamond compact having a common diamond particle diameter of less than 1 micron to further reduce friction.
