Ag+ release and corrosion behavior of zirconium carbonitride coatings with silv...
Calderon Velasquez, S.; Galindo, R. Escobar; Oliveira, J. C.; Cavaleiro, A.; Carvalho, S.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' compositio...
Influence of silver content on the tribomechanical behavior on Ag-TiCN bioactiv...
Sánchez-López, J. C.; Abad, M. D.; Carvalho, I.; Galindo, R. Escobar; Benito, N.; Ribeiro, S.; Henriques, Mariana; Cavaleiro, A.; Carvalho, S.Surface modification of bulk materials used in biomedical applications has become an important prerequisite for better biocompatibility. In particular, to overcome the particle generation, low-wear coatings based on carbon (nitrogen) and containing antimicrobial elements such as silver are promising candidates. Thus, the present work explores the potentialities of silver-containing carbonitride-based (Ag-TiCN) ...
Improving the visible transmittance of low-e titanium nitride based coatings fo...
Yuste, M.; Galindo, R. Escobar; Carvalho, S.; Albella, J. M.; Sánchez, O.Low-emissivity (low-e) coatings on glass are nowadays extensively used for energy saving applications in architectural windows and on solar thermal collectors. In this work the feasibility of TiN-based layers as low-e coatings has been studied. TiN samples were deposited by reactive magnetron sputtering and, in order to improve their optical properties (transmission in the visible range, T and emissivity, ε), w...
Ag-Ti(C,N)-based coatings for biomedical applications : influence of silver con...
Manninen, N. K.; Galindo, R. Escobar; Benito, N.; Figueiredo, N. M.; Cavaleiro, A.; Palacio, C.; Carvalho, S.Ag–TiCN coatings were deposited by dc reactive magnetron sputtering and their structural and morphological properties were evaluated. Compositional analysis showed the existence of Ag–TiCN coatings with different Ag/Ti atomic ratios (ranging from 0 to 1.49). The structural and morphological properties are well correlated with the evolution of Ag/Ti atomic ratio. For the samples with low Ag/Ti atomic ratio (belo...
