Special Issue Information

Dear Colleagues,

Corrosion studies have attracted considerable interest in the areas of materials chemistry and industrial chemistry, as it affects the direct and indirect costs of industry, leading to huge economic setbacks due to the need for repair, maintenance, and even shutdowns due corrosion damage. This new volume is a comprehensive resource that presents new and up-to-date, theoretical, and experimental corrosion inhibition studies.

This Special Issue on “Electrochemical and Computational Methods for Corrosion Protection Processes” seeks high-quality works focusing on an overview of corrosion science and presents computational and experimental studies to mitigate damage from corrosion. Taking an interdisciplinary perspective, this volume is a rich resource of studies and experiments toward solutions that are cost-effective, environmentally friendly, and low in maintenance.

This Special Issue offers important information on the mechanisms of corrosion science in theory and practice as well as a wealth of corrosion prevention and protection methods exploring different types of materials and various methods of corrosion inhibition.

This Special Issue includes, but is not limited to, the following topics:

  • corrosion science;
  • corrosion engineering;
  • corrosion protection;
  • materials;
  • smart coating;
  • advanced coating;
  • biomaterials;
  • molecular dynamics simulation;
  • molecular modeling;
  • tribocorrosion.

Abstract
The present study attempted to investigate the best conditions to use 2-(4-chlorophenyle)-1,4,5-triphenyle-H-imidazole as a corrosion inhibitor of mild steel in a 7% HCl and 20% H2SO4 pickling bath mixture, using chemical, electrochemical, and surface response methodologies in a spherical field.

The present study attempted to investigate the best conditions to use 2-(4-chlorophenyle)-1,4,5-triphenyle-H-imidazole as a corrosion inhibitor of mild steel in a 7% HCl and 20% H2SO4 pickling bath mixture, using chemical, electrochemical, and surface response methodologies in a spherical field. For this, a Doehlert matrix and two principal factors of the Pickling Process were examined. An experimental evaluation was carried out using weight loss, electrochemical impedance spectroscopy, and polarization curve measurements. Impedance diagrams and Bode plots for uninhibited and inhibited systems were analyzed and simulated using the Z-view program, the fitted data obtained closely followed the same pattern as the experimental results. This study demonstrates that the 2-(4-chlorophenyle)-1,4,5-triphenyle-H-imidazole compound is an effective inhibitor for mild steel in pickling bath solutions, and corrosion inhibition efficiency increases with increases in inhibitor concentration to attain 93.2% imidazole at 10−3 M. This is due to the absorbability of Cl− and SO42− present in the pickling bath solution and the synergistic effect between both elements. The response used in the exploitation of the design was the determination of inhibitor efficiency. This was assessed through weight loss measurements and electrochemical studies on samples in the absence and presence of 2-(4-chlorophenyle)-1,4,5-triphenyle-H-imidazole. It has been shown that the compound under investigation is an effective cathodic-type inhibitor of mild steel corrosion in pickling bath mixtures. Therefore, the inhibition efficiency was improved with the concentration of the inhibitor, which depended on the molecular structure. The optimal corrosion inhibition efficiency as a function of variation in 2-(4-chlorophenyle)-1,4,5-triphenyle-H-imidazole concentration and pickling bath temperature was simulated and demonstrated using canonical analysis; the obtained efficiency at 324 K for 6 h was 81.3% for the coded variable and 83.4% for the real variable. The experimental results are based on a real-time system and provide much more precise results than the simulated results. Full article
