This study presents the realization of new type materials based on Zn3Nb2O8 undoped and doped with Er3+ ions designed to improve corrosion inhibition of steel in aggressive media. The thin films structures were obtained on carbon steel through the spin-coating technique. Morphological investigations of thin films were carried out by atomic force microscopy (AFM). The inhibition of a steel corrosion process was evaluated in an aggressive environment of 0.1 M HCl by performing electrochemical investigations such as open circuit potential (OCP) and the potentiodynamic polarization technique. The influence of variations in the cathodic Tafel slopes βc and anodic Tafel slopes βa over the corrosion rates was discussed. The best corrosion inhibition efficiency of 93.3% was realized by the steel electrode covered with spin coating techniques were obtained when the layer was made for the Zn3Nb2O8:Er3+ type structure obtained first by the solid-state method using Zn(NO3)2x4H2O, Nb2O5 and Er(NO3)3x5H2O.
