Abstract

The invention relates to a process and a device for monitoring the change in the surface condition of a metal component in an installation containing an ionic phase, by a modification of the working conditions in the installation, relative to standard working conditions. The equilibrium potential of the component in the ionic phase in the installatoin is applied to one electrode of an electrochemical measuring cell, the electrode and the cell respectively reproducing the metal component and the installation under standard working conditions, and the intensity of the resulting electric current in the measuring cell is measured. The invention applies, in particular, to the monitoring of the corrosion of the wall of a steel pipeline through which a sodium chloride brine passes.
