Abstract

La présente invention concerne un procédé d'obtention d'une surface poreuse de titane convenant aux implants médicaux. Le procédé consiste à exposer la surface de titane à un plasma constitué d'un gaz de plasma réactif, lui-même constitué d'une espèce d'attaque chimique active et d'un gaz de pulvérisation cathodique. L'état du plasma permet de modifier la surface du titane et de lui conférer une porosité superficielle. L'état du plasma permet ainsi d'attaquer chimiquement la surface de titane et d'y effectuer une pulvérisation cathodique.
