“…Nano-HA Ca5(OH)(PO4)3 is a well-known bio-material for bone substitution that is distributed into Ag coating. It is a bioactive implantation material capable of making a straight and fixed bond with bone tissue [10]. The chemical composition and crystal structure of HA are similar to those of human hard tissue, which possesses irreplaceable biological action and biocompatibility [8].…”

Silver-hydroxyapatite (Ag-HA) nanocomposite coating on stainless steel (316L) sheets was prepared by electroless deposition. Several studies have analysed the influence of bath composition on the corrosion behaviour of Ag-HA bio-nanocomposite coating produced by electroless deposition. Therefore, the present study compared the influence of varying concentrations of HA nanoparticles (0.1, 0.3, and 0.5) g/L on the mechanical (microhardness) and chemical (corrosion resistance and ion release) properties of the Ag-HA nanocomposite coating. The Ag-HA nanocomposite coating exhibited a remarkable increase in microhardness from 104.7 Hv to 139.9 Hv at 0.5 g/L HA nanoparticles and improved corrosion resistance, where the corrosion rate was enhanced for the coating from 5.954×10-1 mpy to 2.633×10-2 mpy in the presence of nano-HA. The ion release analysis of the element coating revealed that the nickel content was within the permissible limit in accordance with the amount of Ni permitted to exist inside the human body, and chromium was not found.
