摘要：

Alginate composite coatings containing titania nanopartides (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 ascoated sample exhibited corrosion resistance 3 to 7 times higher than that of uncoated AZ91D. (C) 2015 Elsevier B.V.
