Title: Corrosion resistance of ZrO{sub 2}–TiO{sub 2} nanocomposite multilayer thin films coated on carbon steel in hydrochloric acid solution

Abstract

This work reports the achievement of preparing of x% zirconia (ZrO{sub 2})–titania (TiO{sub 2}) composite coatings with different ZrO{sub 2} percent on the carbon steel by dipping substrates in sol–gel solutions. The prepared coated samples were investigated by various surface techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDAX). Open-circuit potential (OCP), potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) methods were employed to investigate the corrosion resistance of the coated carbon steel substrates in 1.0 M HCl solution at 50 °C. The data showed that, the corrosion protection property is not always proportional to the percent of ZrO{sub 2}. It can be inferred that there is an optimum percent (10%ZrO{sub 2}) for beneficial effects of loading ZrO{sub 2} on the protection efficiency (98.70%), while higher loading percent of ZrO{sub 2} in the sol–gel coating leads to the formation of a fragile film with poor barrier properties. EDAX/SEM suggests that the metal surface was protected through coating with ZrO{sub 2}–TiO{sub 2} composite films. - Highlights: • Sol–gel TiO{sub 2} doped with ZrO{sub 2} films deposited on carbon steel substrate • XRD measurements of x wt.% ZrO{sub 2}–TiO{sub 2} showed the (101)more » peaks broader than that of TiO{sub 2}. • SEM results proved that, the cracking decreases with the number of layers. • The prepared films can improve the corrosion resistance of the carbon steel substrate. • 10%ZrO{sub 2} loading is the optimal percent for useful effects on the corrosion resistance.« less
