A surgical implant comprising: a substrate having an exterior surface and a plurality of layers disposed over the substrate exterior surface. The substrate comprises a polymeric material, and the plurality of layers comprises: an activated substrate surface layer； a valve metal layer； and a porous valve metal oxide layer, wherein the valve metal layer is disposed between the activated substrate layer and the porous valve metal oxide layer. The disclosure provides for a method for producing a polymeric surgical implant. The exterior substrate surface is treated by one or more processes comprising: plasma activation； electron beam irradiation； ultraviolet light； and low energy Ar+ ion beam irradiation； producing an activated substrate surface layer. A plurality of layers is applied over the activated substrate surface layer. The surface is converted by a spark-anodization process in an alkaline bath containing Ca and P ions into a layer of porous valve metal oxide.一種外科用之植入物，其包含：具有外表面之基板及佈置在基板之外表面上的多層。該基板包含聚合材料，且該多層包含：活化之基板表面層；閥金屬層；及多孔閥金屬氧化物層，其中該閥金屬層係佈置在活化基板層與多孔閥金屬氧化物層之間。本揭露內容提供用於製造聚合性外科用之植入物的方法。該基板外表面係藉由包含下列者之一或多種過程處理：電漿活化技術；電子束照射；紫外線；及低能量Ar+離子束照射；產生活化之基板表面層。在該活化之基板表面層外施放多層。該表面係在包含鈣及磷離子之鹼性浴中藉由火花陽極氧化過程(spark-anodization process)轉化成多孔閥金屬氧化物層。
