Special Issue Information

Dear Colleagues,

All over the world researchers and industrial specialists have undertaken titanic efforts in order to decrease undesired degradation resulting from corrosion. For the best approaches to resolving these issues through the application of resistant materials and the reduction of aggressive environments, it is imperative that we first learn as much as possible about the basic chemical, electrochemical, and microbiological degrading processes. It is also necessary to diminish the harmful environmental impacts caused by special anticorrosion chemicals. This is why the inhibition of different types of corrosion by multifunctional inhibitors/coatings is important, as they can control not only metal dissolution but can also decrease microbial adhesion and could function as biostatics or biocides. This Special Issue seeks to gather together papers on advanced, multifunctional smart coating materials and on their application in order to engage with new trends that help advance understanding of degrading mechanisms as well as the inhibition potentials for different types of corrosion.

The aim of this Special Issue is to publish manuscripts on these topics:

  • New materials/nanomaterials for surface (pre)treatments that improve the chemical/electrochemical/microbiological stability of the solid surface;
  • Coatings with anticorrosion and antimicrobial adhesion activity;
  • Innovation in multifunctional coatings—materials, techniques, characterization;
  • Coatings with antimicrobial activity;
  • Non-releasing biostatic/biocidal coatings;
  • New characterization techniques that improve the analysis smart coatings;
  • Visualization of surface coatings by traditional and novel methods.

This study examined the ability of a coating made from nano-CeO2-doped montmorillonite (NCM) nanoclay to inhibit corrosion on carbon steel when immersed in a 1 M HCl solution. The coating was produced by combining CeO2 nanoparticles with montmorillonite nanoclay, and its characteristics were analyzed using SEM and XRD techniques. The corrosion inhibition effects were assessed through weight loss and potentiodynamic polarization (PDP) methods. The findings indicated that the NCM nanoclay serves as an effective inhibitor, exhibiting a mixed-type behavior that impedes both the anodic and cathodic reactions on the steel surface in an acidic environment. The investigation demonstrated that the NCM coating achieved remarkable inhibition efficiencies of 95% (using the weight loss method) and 99% (using the PDP method) in the acidic solution. SEM was utilized to capture images of the surface at various phases of the corrosion inhibition process for mild steel. XRD was employed to analyze the structural properties of the coating’s nanoparticles. This modified and eco-friendly NCM nanoclay has enhanced the corrosion resistance of mild steel in acidic environments. Full article

This study, based on our previous research, aims to quantitatively determine the enhanced protection of austenitic stainless steels against pitting corrosion in NaCl solution by self-assembled molecular (SAM) layers, in their original form and after γ-irradiation. This study focuses on four stainless steels of varying compositions, covered by self-assembled undecenyl phosphonic acid layers. The metal dissolution in corrosion experiments was measured by a special, highly sensitive analytical technique using the inductively coupled plasma–optical emission spectrometry (ICP-OES). The comparison of the dissolved metal ion concentrations measured in the presence of different metals with and without nanocoatings allowed the evaluation of the anticorrosion effectiveness of nanofilms as well as the importance of the alloying elements. The ICP-OES results demonstrated that the quality of layers have a significant impact on anticorrosion efficacy. The γ-irradiated self-assembled layers were the most effective in controlling the dissolution of stainless steels. The mechanisms of the inhibition in the presence of these nanolayers were elucidated by infrared spectroscopy. First of all, it revealed the differences in the adsorption of the undecenyl phosphonic acid self-assembled layer, both with and without γ-irradiation. The other important observation that confirmed the increased anticorrosion efficiency after γ-irradiation proved the formation of a more compact, polymer-like layer over the metal surface. The increased anticorrosion efficacy, defined as the enhancement in Pitting Resistance Equivalent Numbers (PRENs) in the presence of self-assembled layers (either pre- or post-γ-irradiation), can be documented.
