Surface changes of biomaterials are essential for aligning with the biological system’s dynamics and enhancing the effectiveness of bioimplants. Customized surface alterations based on the material’s bonding ability, biocompatibility, and interactions with host cells may have a substantial impact. This investigation uses hydroxyapatite (HAp) with 0, 10, 20, 30, and 40 wt% silver as a thin coating layer on stainless steel (SST) 316 L by electrophoretic deposition preparation at 30 V and 30 min coating duration. The coating’s crystallinity, morphology, and microstructure have been investigated using structural characterization methods such as X-ray diffraction, Scanning electron microscopy, and energy dispersive spectroscopy. The resistance to corrosion of uncoated and coated SST substrates has been assessed using potentiodynamic polarization experiments. The results show that the HAp-nanosilver coating layer increases the SST’s resistance to corrosion in Ringer solution. The HAp 10% silver-coated SST displays a reduction in corrosion current density. These further demonstrate the potential for using HAp and silver-coated stainless steel as a surgical instrument to increase biocompatibility and resistance to corrosion. |
