Patent

CA 2468512

A textured surface and oxidation layer coating on a metallic material is accomplished through the chemical and/or electrochemical etching of the surface to modify the surface texture and an in situ oxidation procedure. The surface is useful for the fabrication of prosthetic devices, particularly medical implants, due to the corrosion and wear resistance imparted by the oxidation layer and the ability to enhance grafting of the implant onto bone imparted by the surface texture.

L'invention concerne un matériau métallique comprenant une surface structurée recouverte d'une couche d'oxydation par gravure chimique et/ou électrochimique de la surface de manière à modifier la texture de celle-ci, ainsi qu'un procédé d'oxydation in situ. La surface est utilisée dans la fabrication de prothèses, en particulier d'implants médicaux, en raison de la résistance à la corrosion et à l'usure qu'offre la couche d'oxydation et de la capacité d'amélioration de la greffe de l'implant dans l'os que permet la texture de la surface.
