Fig. 4From: Biocompatible Ti3Au–Ag/Cu thin film coatings with enhanced mechanical and antimicrobial functionalitySEM surface images of Ti3Au thin films doped with varying Cu/Ag concentrations; a Sample SCu1, b Sample SCu2, c Sample SCu3, d Sample SCu4, e Sample SAg1, f Sample SAg2, g Sample SAg3, and h Sample SAg4. Inset images show increasing Ag agglomeration on the surface with increasing Ag concentration in filmBack to article page
