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.
