Claim 0:
1. A biocompatible alloy implant comprising a biocompatible alloy implant body, the biocompatible alloy implant body comprising:
one or more articulating implant body surfaces,
one or more preformed porous metallic ingrowth structures diffusion bonded to one or more bone-interfacing alloy surfaces of the biocompatible alloy implant body,
a collapsible metallic layer placed between the one or more preformed porous metallic ingrowth structures and the one or more bone-interfacing alloy surfaces of the biocompatible alloy implant body, wherein the collapsible metallic layer is configured to collapse/crumble under compression thereby creating an interface, and
a diffusion-hardened layer on the one or more articulating implant body surfaces,
wherein the one or more articulating implant body surfaces correspond to one or more oxidized surfaces of the biocompatible alloy of the biocompatible alloy implant body,
wherein the one or more preformed porous metallic ingrowth structures comprises (a) a porous metallic pad or (b) a nonporous metallic base and a porous metallic pad.
