Resumo: dc.description.abstractIn this study, the protection against corrosion of carbon steel SAE 1020, promoted by a niobium and titanium oxides coating was investigated. The coating was produced by the Pechini method using different titanium proportions to prepare the resin and calcinating for 1 hour. The samples were characterized by open circuit potential, potentiodynamic anodic polarization, electrochemical impedance spectroscopy, scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. The electrochemical analyses suggested protection against corrosion for the coated samples. The increase of the titanium proportion in the resin increased the protection of the substrate. Morphologic and structural analyses showed the deposition of low cristalinity non-homogenous layer of niobium and titanium oxides. The increase in the titanium proportion resulted in the decrease of defects on the surface.pt_BR
