•TiO2/alginate coating produced by EPD for the first time on AZ91D (Mg alloy)•Fresh coated sample exhibits better corrosion resistance than uncoated alloy.•The coating was deposited without previous surface pretreatment.
Alginate composite coatings containing titania nanoparticles (n-TiO2) intended for biomedical applications were deposited by electrophoretic deposition (EPD) on AZ91D substrates without previous surface pretreatment. Coating composition was analyzed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis. Polarization curves of the coated samples showed a higher corrosion potential and lower current density in comparison to bare AZ91D. Electrochemical impedance spectroscopy (EIS) results revealed that the as-coated sample exhibited corrosion resistance 3 to 7 times higher than that of uncoated AZ91D.
