Corrosion Rate and Down Stream Effect in Liquid Metal Systems

  • Norbert F. Schwarz


One of the problems encountered in the liquid sodium corrosion of austenitic steels and other materials is the dependence of the corrosion rate on the down stream position. This effect has been described in the literature extensively and explanations for this phenomenon have been presented. Accordingly the following causes can be considered to dominate the down stream effect
  • - saturation of metallic element dissolution

  • - consumption of a corrosion inducing agent, e.g. O2

  • - poisoning of active corrosion sites by a corroding or dissolving species

  • - hydraulic phenomena, growth of a laminar sublayer.
