Influence of Current Density on the Morphology and Structure of Silver Nanoparticles on Anodized Titanium for Biomedical Implant Applications

This article focused on investigating the influence of current density on the morphology and structure of silver nanoparticles (n-Ag) electrodeposited on anodized titanium substrates (denoted as TiO 2 /Ti) on the surface. The TiO 2 /Ti substrate served as the cathodic electrode placed in an electrolyte solution containing ionic [Ag(NH 3 ) 2 ] + complex solution. The n-Ag/TiO 2 /Ti samples were synthesized at current densities ranging from 0.2 A/dm 2 to 0.5 A/dm 2 for 20 seconds at room temperature. The study performed morphological and surface composition analysis of n-Ag/TiO 2 /Ti using Field Emission Scanning Electron Microscopy (FESEM) and X-ray Diffraction (XRD) techniques. Additionally, the study assessed the electrochemical properties using the AutoLab system with Nova 2.1 software, based on Tafel curve measurements to compare the corrosion resistance of the samples before and after modification.
