The object of this work was to investigate structure, electrochemical behavior and semiconducting properties of the TiO2 oxide layer on the Ti-15Mo implant alloy surface in normal and inflammatory conditions of physiological saline solution. X-ray photoelectron spectroscopy measurements confirm the presence of the oxide layer on the Ti-15Mo alloy surface. Electrochemical studies indicate excellent corrosion resistance of Ti-15Mo alloy in physiological saline solution. It was found that the investigated material under normal and inflammatory conditions behave like an insulator and n-type semiconductor, respectively.
