Abstract:
A component for a prosthetic joint comprising:a substrate that includes a solvent-catalyst metal, a diamond layer sintered to said substrate, a zone between said substrate and said diamond layer that has a composition gradient of decreasing solvent-catalyst metal content across said zone, chemical bonds in said zone, said chemical bonds including diamond-to-diamond bonds in said diamond table, diamond-to-metal bonds in said gradient transition zone, and metal-to-metal bonds in said solvent-catalyst metal. a mechanical grip between said diamond layer and said substrate which tends to secure said diamond layer to said substrate, interstitial spaces in said diamond layer, solvent-catalyst metal present in said interstitial spaces, and a non-planar load bearing and articulation surface formed by said diamond layer.
