Two-phase alumina nanocomposite electrochemically synthesized as corrosion inhibitor in carbon steel metal for acid media

This study aims to synthesize Alumina α-ɣ Al2O3 nanocomposite by electrolysis method using an aluminum plate as an anode and a graphite rod as a cathode. The Nano-synthesized was examined by transmission electron microscopy (TEM) and powder X-ray diffraction (XRD). The results showed that the mean p...

description This study aims to synthesize Alumina α-ɣ Al2O3 nanocomposite by electrolysis method using an aluminum plate as an anode and a graphite rod as a cathode. The Nano-synthesized was examined by transmission electron microscopy (TEM) and powder X-ray diffraction (XRD). The results showed that the mean particle sizes of the α-ɣ Al2O3 nanocomposite less than 10 nm. The electrochemical behavior of different concentrations of nanocomposite as a carbon steel corrosion inhibitor in HCl at various temperatures. The results have demonstrated that the efficiency of the inhibition increased with increasing nano-inhibitor concentration and low temperature. As the temperature increased, the inhibition efficiency decreased using weight loss and polarization techniques. Inhibitor adsorption forms a layer on the surface of a metal, and the Adsorption is followed by Langmuir isotherm. The thermodynamic parameters in the corrosion inhibition process for this nanocomposite were studied. Excellent results were obtained from the different energies of enthalpy, entropy, activation and free energy of Adsorption on the metal surface.
