Conclusions

  1. 1.

    Selective absorption of hydrogen (at active centers) takes place on the working surface of railway crossing points made of steel G13L.

     
  2. 2.

    High hydrogen concentrations are found in the metal adjacent to exfoliation; these concentrations reach a maximum in layers situated at a distance of 0.5–1 mm from the exfoliation surface.

     
  3. 3.

    In an exfoliation zone the hydrogen concentrations are considerably greater than the initial values.

     
  4. 4.

    “Splashes” of hydrogen concentrations are observed in regions of the surface layers of the crossings in which flakes are not actually visible; the state of the metal can then be described as the preflaking stage.
