Graphene oxide incorporated hydroxyapatite hybrid films were coated on 316L stainless steel substrate with the aid of electrochemical studies at the voltage of −1.5 V for 30 min using three electrode arrangements. Purity and crystallinity of the formed HAP/GO composite coatings were examined using X-ray diffraction and Fourier transform infrared spectroscopic studies. Phase of the hydroxyapatite was not affected with incorporation of graphene oxide into its matrix. Well-ordered and compact coating morphology was observed for the electrochemically deposited HAP/GO on 316L substrate using the scanning electron microscopy. High-resolution transmission electron microscopic studies reveal the tight bonding and growth of HAP particles on to the sidewalls of GO sheets. Electrochemical studies for the HAP/GO composite coating against the physiological solution showed improved corrosion efficiency. Addition of GO into HAP enhances the apatite precipitation and bone-bonding ability. These results concluded that the electrochemical deposition of bioceramic coatings on implant may be treated as an effective method for orthopedic repair and replacements. © 2021, Institute of Chemistry, Slovak Academy of Sciences.
