Special Issue Information

Dear Colleagues,

Corrosion inhibitors are substances that are used to slow down or prevent the degradation of materials caused by corrosion. Corrosion inhibitors work by forming a protective barrier on the surface of the metal, thus reducing the rate of corrosion.

The aim of this issue is to consolidate recent findings related to corrosion and the deterioration of materials and to give the opportunity to researchers to publish their latest results on understanding or solving the corrosion problems of materials using corrosion inhibitors complemented by theoretical approaches. We invite high-quality original papers and critical reviews.

Potential topics include, but are not limited to, the following areas:

  • Corrosion fundamentals;
  • Corrosion mechanisms;
  • Industrial processes;
  • Corrosion inhibition;
  • Corrosion monitoring techniques;
  • Surface characterization;
  • Theoretical approaches.

Abstract: This work is based on the synthesis of eco-friendly Schiff bases from the imidazole family, serving as anticorrosion agents for mild steel in a 1M HCl solution. The Schiff base derivatives, IM1 and IM2, function as bioactive inhibitors, enhancing their efficacy against corrosion in acidic environments. Molecular structures are confirmed through chemical analyses, including NMR and mass spectroscopy. Electrochemical evaluations demonstrate robust corrosion inhibition of mild steel in a corrosive 1M HCl solution using the synthesized ligands. Electrochemical results reveal excellent inhibition by compounds IM1 and IM2 (98% and 92% respectively) at 10-3M. These findings are corroborated by the observation of the protective layer formed during extended immersion of mild steel in a corrosive solution, with or without inhibitors. Lastly, theoretical studies (DFT, molecular simulations) analyze the adsorption of IM1 and IM2 onto the iron surface, providing insights into the inhibitor-metal interaction during corrosion inhibition.
