Electrochemical Behavior and Corrosion Resistance of 12Cr18Ni10Ti Austenitic Steel after Thermal and Neutron Exposure

The effect of annealing and neutron irradiation parameters on changes in the microstructure and corrosion properties of the 12Cr18Ni10Ti austenitic steel has been studied. The values of steady-state potentials, as well as the potentials of passivation, activation, and stable pitting, of the steel in various structural states have been provided. The dependences of the anode current density on voltage have been established. It has been shown that the electrochemical behavior and corrosion resistance of the steel in a chloride-containing medium depend on the intensity of redox processes on the metal surface as well as on the state of the structure at the micro- and nanolevel.
