ABSTRACT:
This document discloses a method for bonding a calcium phosphate coating to stainless steels or cobalt base alloys for bioactive fixation of artificial implants. The method consists essentially of the following successive steps: applying and thermally diffusing a layer of titanium or its alloys into the stainless steel or cobalt base alloy substrates, applying a calcium phosphate coating and thermally diffusing Ca.sup.2+ and PO.sub.4.sup.-3 ions of the calcium phosphate into the intermediate layer of the titanium or its alloys and finally, the hydrothermal processing of the calcium phosphate coating.
