Abstract

Silver containing coating can represent a solution to the recurring problem of biofilm formation on implant surfaces. In this study, the development of a titanium oxide coating containing silver particles is reported. The coating was obtained on medical grade Ti-6Al-4V alloy by anodic spark deposition in an aqueous electrolyte. Surface characterization revealed a high specific surface area with a succession of flat plateaus and depressions. Silver was present all over the coating surface as small particles of sizes below 200. nm. When immersed in a liquid medium, the coating released silver ions at a constant rate over more than 15. days. The coating was able to show a complete killing of gentamicin-resistant Staphylococcus epidermidis within the first 12. h after inoculation.
