Abstract Scope |
Diamond-like carbon (DLC) coatings with incorporated silver nanoparticles were deposited on Ti6Al4V substrates using the DC-pulsed plasma enhanced chemical vapor deposition (PECVD) technique with an additional cathode. The microstructural, mechanical, tribological, anticorrosive, bactericidal properties, and adhesion to the substrate were studied. Well-adhering coatings were achieved displaying high values of hardness and modulus of elasticity. Additionally, they presented attractive tribological properties, low coefficient of friction and high wear resistance. Comparing with undoped DLC coatings, the addition of silver nanoparticles led to a significant increase in the anticorrosive protection and the bactericidal properties. Bacterial reductions were observed both in the colony-forming-unit (CFU) tests and in the scanning electron microscopy (SEM) micrographs. These results highlight that silver doped carbon coatings are promising candidates to be used in important industrial, biomedical and pharmaceutical applications. |
