Abstract
A biocompatible implant for medical use having a layer of titanium or titanium alloys on its surface. The implant is electrochemically treated by using it for an anode in an electrolyte solution containing calcium ions so as to produce a layer of hydrated oxides or hydrated oxide gels, or is subject to an anodic treatment. Subsequently the implant is subject to another electrochemical surface treatment where the implant is employed as a cathode so as to yield a layer that involves or is adsorbed with calcium ions, thus forming on the implant a hydrated gel layer that has an excellent ability of forming apatite.
