Silver-containing porous layers were fabricated on 6061 aluminum alloy via electrochemical pore formation followed by Ag⁺ deposition. The influence of deposition time on phase composition, microstructure, wear resistance, corrosion resistance, and antibacterial activity was evaluated using phase analysis, scanning electron microscopy (SEM), wear testing, electrochemical corrosion measurements, and antibacterial assays. Silver-bearing phases (Ag, Ag₂O, and Ag₂SO₄) appeared as white, block-like features that evolved into flocculent, cotton-like morphologies with increasing deposition time. At a deposition time of 5 min, the Ag content reached 2.28 wt.%, with a corresponding friction coefficient of 0.50, corrosion potential of −0.473 V, and antibacterial rate of 99.82%. These results indicate that extending the Ag⁺ deposition time enhances the tribological and electrochemical performance of 6061 aluminum alloy, and that the samples exhibit remarkable antibacterial properties.
