The present invention relates to a process for grafting polymers onto a metallic material, comprising the following steps: a) oxidation of the surface of the metallic material, resulting in an oxidized metallic material; b) grafting of a polymer at the surface of said oxidized metallic material by radical polymerization of a monomer, said radical polymerization comprising an initiation step and a propagation step, said initiation step being carried out by UV irradiation with a UV source diffusing a power at the surface of the material of greater than 72 mW.cm -2 , said UV irradiation being carried out for a duration greater than 15 minutes and less than 180 minutes, said process resulting in a grafted metallic material. The present invention also relates to the materials capable of being obtained by this process, and applications of the latter, in particular as articular or dental implants. |
