Abstract

The present work mainly focused on developing composited niobium ion 58S bioglass with functionalized multiwall carbon nanotube (MCNTs) surface modification by bioceramic composite coatings on the metallic substrate 316L SS using electrophoretic deposition for load-bearing applications in orthopedics and dentistry. The composited 58S bioglass material was prepared using classical sol-gel technology by adopting condensation and polymerization process; the resultant 58S bioglass was used for the preparation of MCNTs composite by ultrasonication technique. The obtained composite was taken for the coating on the surface-modified 316L SS substrate. The bioactive composite coatings were developed through electrophoretic deposition on 316L SS metallic substrates and were analyzed by FT-IR spectroscopy, XRD analysis, Raman analysis, and FESEM analysis. Further, tested for the corrosion resistance in SBF by potentiodynamic polarization and electrochemical impedance spectroscopy. The composite coatings on metallic substrates showed improved electrochemical properties in the simulated body fluid environment when compared with the bare substrate. The surface morphological analysis revealed crake-free intact coatings on the substrate material, which is one of the essentially required features for coated metallic implants for clinical applications. The apatite formation on the surface of the coating has been observed while immersion in an SBF environment with fixed intervals.
