Special Issue Information

Dear Colleagues,

Electrochemical corrosion characteristics and newly developed protection measures for different metal-based materials are critical to advancing sustainable technology, infrastructure durability, and functional material science. This Special Issue, titled "Advancements in Electrochemistry and Corrosion Protection", aims to showcase the innovative integration of cutting-edge developments of electrochemistry with emerging strategies in the theory, methods, and techniques of corrosion protection of metal-based and other functional materials.

This Special Issue covers a broad spectrum of topics, ranging from fundamental mechanistic studies to advanced technological applications. A key focus is on how emerging electrochemical methods—such as in situ/operando electrochemistry—are being combined with new concepts in corrosion protection, including the design of protective films, high-performance anti-corrosion materials, and eco-friendly inhibitors. By integrating these frontier developments, this Special Issue provides deep mechanistic insights while offering practical solutions to extend service life and enhance safety.

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

  • Fundamental Electrochemical Theory (especially for corrosion electrochemistry);
  • In situ/operando corrosion monitoring techniques at the surface/interface of corroding metal electrodes;
  • Corrosion behavior at the micro- and nanoscale;
  • Organic coatings, conversion layers, and new types of electrochemical barriers;
  • Synthesis, characterization, and electrochemical evaluation of new corrosion inhibitors;
  • Fundamental and applied studies in cathodic/anodic protection;
  • Other corrosion mechanisms of advanced functional materials.

I look forward to receiving your contributions.

This study examined the stress corrosion of Alloy 625 in Cl + S2O32− solutions using digital holography in combination with electrochemical methods. Without elastic tensile stress, intergranular corrosion (IGC) occurred, due to the higher activity of grain boundaries compared to the grain interior and to preferential adsorption of sulfur (produced by S2O32− decomposition) at these boundaries. Digital holography observations showed that IGC initiated at certain grain boundaries and propagated to adjacent boundaries, even in the absence of elastic tensile deformation. Applying elastic tensile stress (260 MPa, ~46% σy) increased the defect density within the oxide film, thereby enhancing corrosion and anodic currents, and inducing river-like cracks. Although elastic tensile stress suppressed IGC, it simultaneously promoted stress corrosion cracking (SCC), as the stress exerted a stronger accelerating effect on corrosion than the grain-boundary did. Digital holography allowed in situ monitoring of the stress corrosion process in Alloy 625, demonstrating that cracks initiated via localized corrosion/IGC and subsequently propagated along the direction of the applied stress.
