Titanium alloy implants are essential for bone replacement surgeries; however, they are susceptible to infection. To improve their antimicrobial properties, we develop graphene-based coatings on the implant substrates (alloy Ti6Al4V), taking advantage of the antibacterial and biocompatible properties of graphene (G) or graphene oxide (GO). For this purpose, the titanium alloy is coated with G or GO nanosheets using different coating techniques like double self-assembly procedure and electrochemical deposition. The coatings are characterized using complementary characterization techniques including scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, atomic force microscopy (AFM) and optical microscopy. The morphological and chemical properties of the obtained graphene coatings are analyzed in respect to their growth conditions to elucidate influences on the quality, uniformity, and possible biofunctional performance.
