Surgical implant comprising a substrate having a plurality of layers disposed on the outer surface of the outer surface and the substrate. The substrate comprises a polymeric material, a plurality of layers activating the substrate surface layer, valve metal layer, and comprising a porous valve metal oxide layer, valve metal layer has the porous valve genus oxide activated substrate layer It is disposed between the object layer. The present disclosure provides a method of making a polymeric surgical implants. The outer surface of the substrate, plasma activation, electron beam radiation, ultraviolet light, and low energy Ar + ion beam irradiation, processed by one or more processes, including to produce an activated substrate surface layer. Multiple layers are applied onto the activated substrate surface layer. Surface is converted by spark anodization process in an alkali bath containing Ca and P ions into the layer of porous valve metal oxide.
