Research on Theoretically Modelling and Quantitatively Calculating Stray Current Corrosion in a Subway System

open access: yesInternational 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

Evaluation of DC-Subway Stray Current Corrosion With Integrated Multi-Physical Modeling and Electrochemical Analysis

open access: yesIEEE Access, 2019
Leakage of stray current can cause serious problems by accelerating the corrosion process of a buried pipeline in the subway. A multi-physical finite element model of the DC-subway traction system was established in this study, and the dynamic process of

Corrosion and stray currents at urban track infrastructure [PDF]

open access: yesGrađevinar, 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

Effect of Stray Current on Corrosion and Calcium Ion Corrosion of Concrete Reinforcement

open access: yesMaterials, 2022
The construction of subways, hydroelectric stations and water substations is exposed to stray currents, which can accelerate concrete corrosion. The influence of stray currents on reinforced concrete structures is unclear. In this paper, the influence of concrete strength grade, reinforcement diameter and stray current intensity on the extent of ...
