International Journal of Electrochemical Science, 2020 To investigate the effect of stray current in subways on the corrosion of buried pipelines near tracks, a 3D-finite element method (FEM) model of stray current distribution for one subway interval was established. Under the operation conditions of subway

Study on the Corrosion Behavior of X65 Steel Under Cathodic Protection Influenced by Simulated Stray Current Interference [PDF]
Cailiao BaohuThe operation of the subway train system can leak stray currents, causing fluctuations in the potential of nearby buried metal,weakening or even failing the cathodic protection effect, and ultimately leading to the failure of buried metal due to ...

Corrosion and stray currents at urban track infrastructure [PDF]
Građevinar, 2020 Rails are a part of track structure where corrosion process inevitably occurs, except if they are fully insulated and devoid of contact with any other part of the structure (sleepers, fastening accessories) or electrolyte like moist soil or water in track structure. Corrosion occurs much faster in the presence of stray currents, which very soon results
