A surface coating strategy encompassing the use of bioactive trace elements and reinforcing material will have significant influence on mechanical and osseointegration properties of bioceramic coated implants. Here, We attempted to mimic developed a minerals substituted and graphene oxide reinforced hydroxyapatite (Se,Mn-HAP/GO) composite coating on titanium (Ti) by electrodeposition which is a promising approach to produce bioimplants with better osseointegration capacity and improved mechanical property. Mechanical and biological studies were used to characterise the coatings. The composite coating on Ti was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM). Also, the corrosion resistance of the coatings was evaluated by electrochemical techniques in simulated body fluid (SBF) solution. The in vitro cell-material interaction of the composite coating was observed with human osteosarcoma MG63 cells for cell viability at 1, 2 and 3 days of incubation. From the results we believe that the (Se,Mn-HAP/GO) composite coating on Ti could provide effective corrosion protection, enhanced bioactivity. Thus, composite coated Ti can serve as a potential candidate for orthopedic applications.
