A prosthetic joint (108, 130) with polycrystalline diamond compact coated interfaces (150, 158) and a method for making the same are disclosed. The prosthetic joint (108, 130) has a diamond layer (150, 158) formed on at least one of the interacting, load-bearing surfaces of the joint (108, 130). The diamond layer (150, 158) adds resistance to damage from impacts and, when polished, gives the joint a low coefficient of friction, thereby increasing the life of the joint (108, 130). 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. |
