摘要：
The present invention relates generally to an antibacterial coating which iscomposed of silver, to medical toolsand to implants comprising such a coating and to a method as well to anapparatus for the production of such a coating. The medicaltools or the dental or orthopaedic implant comprises a metal or metal alloyhaving a treated surface wherein the treated surfaceis at least partially converted to an oxide film by plasma electrolyticoxidation using a colloid-dispersed system and wherein theconverted surface is partially covered by islands formed by colloid-dispersedsilver-particles of the colloid-dispersed system. AnAg-TiO2 coating according to the invention shows excellent properties in termsof antibacterial efficacy (even against multi-resistantstrains), adhesion and biocompatibility. The life-time of an implant in ahuman body is increased. The antibacterial coatingcan be used in the field of traumatology, orthopaedic, osteosynthesis and/orendoprothesis, especially where high infection risk exists.A high number of currently existing medical tools and implants can benefitfrom such a coating.
