Corrosion, leading to accelerated material degradation and failure, carries vast financial and safety risks in modern society. Corrosion is a very common and natural process that deteriorates materials via chemical/electrochemical reactions between the materials (e.g., metals, ceramics, amorphous materials) and their surrounding environments. Unseen and unmitigated corrosion of in-service materials can drive unexpected costs and shutdowns in industrial settings (e.g., part replacement, loss of efficiency), or far more catastrophic consequences (infrastructure collapse, pipeline failures, biological effects from medical implants and environmental pollution). The risks associated with corrosion are best exemplified by the nuclear industry, with potential consequences ranging from plant operations to the safe disposal of nuclear wastes.

The research community has been devoted to identifying, tracking, and mitigating corrosion issues across nearly all industries to minimize risk. The focus of these efforts has been placed on a variety of processes including, but not limited to, general corrosion, pitting corrosion, crevice corrosion, galvanic corrosion, stress corrosion cracking, and corrosion fatigue. In all of these corrosion processes, the characterization of the corroding interface of the material in contact with the environment is the most important step to understand corrosion behaviour, to identify the controlling mechanisms, and to find solutions for material protection.

The aim of this Special Issue is to consolidate recent findings related to interfacial corrosion processes using scanning techniques (e.g., SEM/EDS, EDSB, KPFM, STEM, SVET), and to provide a platform for researchers to publish the lasted findings, reviews, research methodology to solve the fundamental scientific corrosion issues. We welcome the submission of original papers and critical reviews.

Potential topics include but are not limited to the following:

• Corrosion fundamentals
• High temperature oxidation
• Anodic oxidation
• Biochemical corrosion
• Stress corrosion cracking, corrosion fatigue, and corrosion creep
• Corrosion control and protection
