Abstract : In the present investigation, the surface of Ti-15Mo (β-Ti) alloy was oxidized using hydrogen peroxide (H2O2) and the layer was densified by thermal treatment. Morphological characterization of treated surface by Field Emission Scanning Electron Microscope (FE-SEM) revealed the formation of nanoporous layer. Electrochemical studies of H2O 2 treated specimen exhibited higher corrosion resistance in simulated body fluid (SBF) solution compared to untreated β-Ti alloy. Further, the formation of nanoporous layer and their electrical components were evinced from impedance studies by fitting it to an circuit model. © Springer Science+Business Media, LLC 2011.
