Anti-Microbial Bioceramic Coatings on Ti6Al4V Surfaces by Anodisation

Titanium and its alloys are a popular choice for biomedical implants, particularly knee and hip replacements, owing to their high biocompatibility and superior mechanical properties. The insertion of these implants is done through surgery and the resulting incisions provide an entry point for microbes, thereby increasing the risk of infections andrejection responses. These infections are difficult to treat and impact severely on patient health and implant lifetime. A potential solution is the fabrication of anti-microbial coatings of TiO2 on the implant surface which are photocatalytic and can be activated by X-rays to provide an anti-microbial effect
