Special Issue Information

Dear Colleagues,

The corrosion of metals and alloys remains one of the most persistent challenges affecting a wide range of sectors, including infrastructure, energy, transportation, and manufacturing. The degradation of metallic materials leads not only to significant economic losses but also to safety hazards and environmental concerns. Understanding corrosion mechanisms and developing efficient, sustainable protection strategies is therefore essential for advancing modern technologies and ensuring the long-term reliability of engineered systems.

We are pleased to invite you to contribute to this Special Issue on “Corrosion Mitigation and Protection of Metals and Alloys,” which seeks to showcase the latest research developments and innovative solutions in this critical field.

This Special Issue aims to highlight recent advances in corrosion science, mitigation strategies, and protective technologies that enhance the performance and durability of metallic materials. It aligns with the scope of Materials, which covers the design, characterization, processing, and application of advanced materials. Contributions exploring corrosion mechanisms, electrochemical behavior, advanced coatings, inhibitors, modeling, and environmentally friendly protection methods are particularly encouraged. The Special Issue seeks to bridge fundamental understanding with practical engineering solutions to support sustainable material design and long-term performance.

In this Special Issue, original research articles and review papers are welcome. Research areas may include, but are not limited to, the following:

  • Corrosion mechanisms and electrochemical analysis;
  • Protective coatings and surface engineering;
  • Green and sustainable corrosion inhibitors;
  • Nanomaterials for corrosion protection;
  • High-temperature or marine corrosion;
  • Modeling, simulation, and predictive approaches;
  • Smart/self-healing protective systems;
  • Corrosion behavior in harsh or industrial environments.

We look forward to receiving your valuable contributions.

Polyphenol-Driven Interfacial Control: How Achillea millefolium Extract Modulates Mild Carbon Steel Corrosion in Acid and Neutral Media
by Gabriela Elena Badea, Ioana Maior, Anda Ioana Grațiela Petrehele, Oana Delia Stănășel, Alexandrina Fodor, Mioara Sebeșan, Simona Dzitac and Camelia Daniela Ionaș

Abstract
Plant-derived corrosion inhibitors are increasingly investigated due to their rich content of adsorption-active phytochemicals. Four extracts obtained from Achillea millefolium were biochemically characterized through spectrophotometric and chromatographic analyses, confirming a substantial polyphenolic content and associated antioxidant capacity. In addition, the hydroethanolic extract (1:1) [...] Read more.
Plant-derived corrosion inhibitors are increasingly investigated due to their rich content of adsorption-active phytochemicals. Four extracts obtained from Achillea millefolium were biochemically characterized through spectrophotometric and chromatographic analyses, confirming a substantial polyphenolic content and associated antioxidant capacity. In addition, the hydroethanolic extract (1:1) was examined for its ability to inhibit the corrosion of S235 mild steel in 1 M HCl and neutral medium of 3.5% NaCl by gravimetry, potentiodynamic polarization, open-circuit potential, and electrochemical impedance spectroscopy methods, suggesting that its antioxidant molecules may contribute to the passivation of the metal surface, but in different mechanistic ways. The inhibitory efficiency determined by both the gravimetric method and the Taffel polarization curve method reaches values of 78.53% in HCl 1 M and of 79.65% in NaCl 3.5%, thus demonstrating the contribution of polyphenols from the Achillea millefolium extracts to the inhibition of corrosion.

In this study, first-principles calculations were employed to systematically investigate the adsorption of Cl on Al2Cu(110) surfaces, clean Al(111)/Al2Cu(110) interfaces, and Fe/Si-doped interfaces, as well as the influence of strain on interfacial electronic structure and corrosion activity. When Cl is adsorbed on Al sites, the bonding between Cl and Al exhibits strong ionic characteristics with localized charge transfer, while adsorption on Cu sites is characterized by more delocalized, covalent interactions. This competition dictates the site-dependent stability of adsorption. Through geometric–electronic synergy, the interface functions as both a “Cl enrichment zone” and an “activity source,” significantly favoring Cl adsorption at high-activity anodic sites such as Al-hole and Al-bridge. Conversely, Cu-top sites maintain a high work function and an inert cathodic nature, facilitating the formation of efficient micro-galvanic couples across the interface. Moreover, Fe/Si doping further modulates the interfacial electronic landscape: Si serves as an effective strengthening element due to its low substitution energy and high stability, while Fe primarily forms a solid solution on the Al side, potentially introducing galvanic corrosion risks. Stress analysis indicates that tensile strain systematically enhances surface activity by lowering the work function, while compressive strain non-monotonically influences corrosion through a three-stage mechanism involving the “densification–cracking–plastic relaxation” of the passive film. These findings elucidate the atomistic origins of corrosion initiation at Cu–Al composite interfaces and provide a theoretical foundation for enhancing corrosion resistance through alloy design and strain engineering.
