Abstract
This paper dealt with two newly done nano-composite films, the first composed of chitosan nanoparticles (CNP) and the second composed of chitosan nanoparticles modified with silver nanoparticles (CNP+SNP), each one is coated on bare Ti alloy surface. Electrochemical impedance spectroscopy (EIS) and Tafel tests were accomplished to identify the corrosion behavior of the bare Ti alloy surface and the synthesized nano-composite coatings on titanium alloy surface in artificial saliva solution. The morphology of the alloy surface coating was achieved. Besides that, the antibacterial activity for the nano-coatings were examined and linked with the bare Ti alloy. The overall results showed that both the two novel coatings enhance the corrosion protection and the antibacterial activity of the studied alloy, where the corrosion resistance and the antibacterial activity of (CNP+SNP) nano-composite coating is remarkably greater than CNP coating.
