摘要：
The present invention relates generally to an antibacterial coating which is composed of silver, to medical tools and to implants comprising such a coating and to a method as well to an apparatus for the production of such a coating. The medical tools or the dental or orthopaedic implant comprises a metal or metal alloy having a treated surface wherein the treated surface is at least partially converted to an oxide film by plasma electrolytic oxidation using a colloid-dispersed system and wherein the converted surface is partially covered by islands formed by colloid-dispersed silver-particles of the colloid-dispersed system. An Ag-TiO coating according to the invention shows excellent properties in terms of antibacterial efficacy (even against multi-resistant strains), adhesion and biocompatibility. The life-time of an implant in a human body is increased. The antibacterial coating can be used in the field of traumatology, orthopaedic, osteosynthesis and/or endoprothesis, especially where high infection risk exists. A high number of currently existing medical tools and implants can benefit from such a coating.
