The surface state assessment in corrosion equipment monitoring

Abstract

A periodic potentiostatic monitoring mode of the chromium-nickel steels surface state under the pitting corrosion is proposed. The scalar impedance angular coefficient calculated on the basis of the spectral analysis method application is shown to be used for assessing the chromium-nickel steel surface state. The software module used for calculating the studied steel grades angular coefficient values was developed and the module limit values characterizing the surface state were defined.A periodic potentiostatic monitoring mode of the chromium-nickel steels surface state under the pitting corrosion is proposed.
