ABSTRACT:
Anti-microbial coatings and method of forming same on medical devices. The coatings are formed by depositing a biocompatible metal by physical vapor deposition techniques to produce atomic disorder in the coating such that a sustained release of metal ions sufficient to produce an anti-microbial effect is achieved. Preferred deposition conditions to achieve atomic disorder include a lower than normal substrate temperature, and one or more of a higher than normal working gas pressure and a lower than normal angle of incidence of coating flux.
