Thermogalvanic effects in corrosion in supercritical water

Conference ·
OSTI ID:350170

The importance of thermogalvanic corrosion mechanism in supercritical aqueous solutions is demonstrated. Large temperature gradients in the reactors coupled with the changes in the solution conductivity and density around critical point of water result in the formation of the thermogalvanic concentration cells. The thermogalvanic concentration cells contribute to the remarkable spatial distribution of the corrosion damage in SCWO systems. Approaches to the mitigation of corrosion in SCWO based on the thermogalvanic corrosion mechanism are discussed.
