“…The stray current leakage is high in low soil resistivity areas and the leakage of DC power from operating transit systems is significantly high compared to AC transit systems. The current travels to unintended bath owing to low resistivity through railway structure, and it makes material degradation (through electron loss) where it leaves from the structure [42,43]. Application of protective coatings are a common means for railway structure corrosion mitigation.…”

Detecting and monitoring of corrosion is one of the major challenges in insulated metallic structures or structures with one or more than one interface. This review paper aims to consolidate scattered literature on laboratory system-based corrosion measurement at the interface region. There are range of sensor-based detection and monitoring methods (active, passive) for corrosion rate analysis, including those which measures a surrogate, i.e. quantifying moisture, temperature, pH and qualify other changes or degradations at the interface. With the emergence of a novel application of advanced sensing methods, this review also presents the possibility of the application of hybrid and multifunctional sensing methods at the interfaces, aimed at advancing corrosion monitoring at the interface region. Key research areas of development relating to the application of combination of other materials (e.g. metal oxides, carbon nanotubes, metal nanowires, piezoelectric) as potential sensors and their impact on existing practices in the field are identified.

The corrosion of metals in concrete is a multibillion dollar problem which affects the construction, transportation, and many other industries. While much has been written about the problem, and numerous reports have appeared which discuss how this corrosion can be controlled, little has appeared on the mechanism whereby this corrosion occurs. It is well known that highway structures corrode, for the most part, due to the influence of deicing salts or marine environments. Relatively little has appeared about the equally severe corrosion problems which occur in buildings and other nonhighway structures. Most of these structures are not exposed to the salts present in highway structures, yet they still corrode. This paper discusses how all forms of concrete and similar cementitious environments protect embedded metals. It discusses the three protection mechanisms—passive film formation, changes in the conductivity of the electrolyte, and mineral scales—that have been used to explain how corrosion in concrete occurs. It also presents evidence to explain how, and why, corrosion occurs in these structures, even in the absence of deicing salts, marine environments, or other salt sources. Examples are discussed including buildings, marine piers, foundations, and highway structures.
