Material analysis of steel corrosion products in water coolants of thermal and nuclear power plants

摘要

The poor informativity of conventional elemental analysis in the industrial control of equipment corrosion at thermal and nuclear power plants was discussed. A set of methods was proposed for the material analysis of steel corrosion products. The set includes spectrophotometry for determining the chemical composition of hydroxo complexes in aqueous solutions and various versions of Mossbauer spectroscopy for identifying and determining corrosion products in the solid phase of suspensions, loose deposits, and corrosion films on steel surfaces.
