| Popis: | Zirconium carbonitride coatings with silver nanoparticles were produced by DC unbalanced dual magnetron sputtering system, using two targets, Zr and Zr/Ag in an Ar, C2H2 and N2 atmosphere. Stainless steel 316L and silicon (100) substrates were used for electrochemical and structural characterization, respectively. Silver was found to be well distributed throughout the coatings, maintaining the films' composition in depth, while its diffusion to the electrolyte decreases as immersion time increases, stopping its release after 7 to 8days of immersion. Electrochemical characterization revealed very stable films that have improved base material, without any diminished corrosion resistance due to the silver content. https://doi.org/10.1016/j.surfcoat.2013.02.011 This research is partially sponsored by FEDER funds through the program COMPETE—Programa Operacional Factores de Competitividade and by Portuguese national funds through FCT—Fundação para a Ciência e a Tecnologia, under the project ANTIMICROBCOAT—PTDC/CTM/102853/2008.
