Impact of porosity and thickness of nano‐TiO₂ films on the corrosion protection performance of C‐steel in H₂SO₄

Abstract

The current study investigates the improvement in the corrosion protection performance of C‐steel after being dip‐coated with nano films from both pure TiO2 and poly ethylene glycol (PEG) modified TiO2. Characterization of the deposited TiO2 films was performed by different techniques. Effect of morphology, porosity, and thickness of the deposited TiO2 layers were also studied. Results revealed an increased corrosion protection of both coated TiO2 films as compared to uncoated samples, with pure TiO2 (without PEG) samples showing higher protection. Moreover, increasing the layer thickness of both types of TiO2 coated films improved the protective properties.

Surface modification of metal mesh with SiO2 films for enhanced corrosion protection

“…The electrochemical parameters such as corrosion potential (E corr ), corrosion current density (J corr ), cathodic and anodic Tafel slope (β c and β a ), polarization resistance (R p ) and the protection efficiency (PE%) were obtained from polarization curves by extrapolation method (Table ). The calculation of protection efficiency (PE %) was using the following expression:…”

Experimental and In-Silico Computational Modeling of Cerium Oxide Nanoparticles Functionalized by Gelatin as an Eco-Friendly Anti-Corrosion Barrier on X60 Steel Alloys in Acidic Environments

“…Nevertheless, under acidic circumstances, steel corrosion is a major issue [2]. This is a particular problem in the oil industry, where X60 steel alloys (steel pipelines) are utilized for the pickling process with inorganic acids (for example HCl and other inorganic acids [3][4][5]. Consequently, inspections of the metal corrosion in hydrochloric acid are of manufacturing significance [6].…”
