Abstract

Abstract The corrosion rate of alloy C-22 in the NaCl solution at room temperature is determined by two methods: by the anodic current density in the potential range of alloy passivity and by the analysis of anodic and cathodic voltammograms measured in the vicinity of corrosion potential. The specific features of passive current determination are considered and the difference between the corrosion currents determined by two methods is explained.
