Zusammenfassung:Acid, neutral salt, and alkaline anodizing treatments are described in addition to relevant industry standards. Surface attributes that have been established for anodized surgical implants include thickness (color), composition, and film growth. Electrochemical and oxide resistivity studies suggest that anodizing promotes improved film stability and enhanced corrosion resistance. Rotating bending fatigue data is documented for notched and smooth specimens that have a machined or anodized surface. Superior in vitro fretting corrosion results have been obtained for anodized titanium implants when compared to electropolished stainless steel. Histological evaluation of rabbit tibia/implant interfaces indicate a favorable biological response. Cell culture studies suggest normal soft tissue adhesion patterns associated with anodized surfaces.
