Advanced surface characterization of silver nanocluster segregation in Ag-TiCN ...
Escobar Galindo, R.; Manninen, N. K.; Palacio, C.; Carvalho, S.Surface modification by means of wear protective and antibacterial coatings represents, nowadays, a crucial challenge in the biomaterials field in order to enhance the lifetime of bio-devices. It is possible to tailor the properties of the material by using an appropriate combination of high wear resistance (e.g., nitride or carbide coatings) and biocide agents (e.g., noble metals as silver) to fulfill its fina...
Influence of ag content on mechanical and tribological behavior of DLC coatings
Manninen, N. K.; Ribeiro, F.; Escudeiro, A.; Polcar, T.; Carvalho, S.; Cavaleiro, A.Ag–DLC coatings with Ag contents ranging from 1.3 at.% to 13.1 at.% were deposited by DC magnetron sputtering. The coatings were characterized with respect to their structure (by means of XRD and Raman spectroscopy), mechanical and tribological properties (by scratch test, nanoindentation, residual stress measurements and pin-on-disk test). The incorporation of 13.1 at.% Ag resulted in the formation of Ag grain...
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...
