High performance nano hydroxyapatite coating on zinc for biomedical applications

Abstract Zinc and its alloys have been given promising consideration as a new biodegradable implant for use in the human body. Compact uniform nano hydroxyapatite coatings containing chitosan were successfully deposited onto zinc substrate an aqueous solution utilizing microwave-assisted process about 10 min. The quick composite are derived by microwave heating compared with electrodeposition. as-deposited formed electrodeposition synthesis known brushite, which was converted to after 1 h of immersion (post treated) M sodium hydroxide solutions at 100 °C. incorporation (from 0.01–0.05 g/l) into coating composition results smooth structure. SEM, EDS, X-ray diffractometer utilized analyze coated samples' surfaces evaluate their surface morphology, chemical composition, crystalline structures. vitro degradation behavior composite-coated samples simulated body fluid pH 7.4 37 °C evaluated using electrochemical impedance spectroscopy potentiodynamic polarization. outcomes showed that microwave-derived provided superior corrosion resistance implants electrodeposited coatings. Furthermore, increased performance. Low concentrations (0.01–0.03 exhibit anti-corrosion properties than higher (0.05 g/l). Against Staphylococcus aureus, demonstrated strong antibacterial efficacy. These fruitful deposition hydroxyapatite/chitosan on indicate is efficient creation either functional or regenerative medicine. resultant may be excellent option bone implants.
