The assessment of negative impact of oil products on railroad track and rolling stock constructions

Abstract

In order to ensure the reliability of metal elements in structures of railway infrastructure, the influence of solutions is investigated that contain oil products on the degree of corrosive changes of steels of grade 3, 5, RSt37-2, 09G2D and grey cast iron 21-40. On the basis of experimental data that were obtained using R-5126 polarization resistance indicator, potentiostat P-5827 mathematical relations of the influence of various fractions of oil products on the rate of metal corrosion are introduced. The obtained data can be used for non-destructive control of basic elements of structures, the choice of effective inhibitors for reducing the corrosive aggressiveness of the environment and the protection of structural elements.
