Abstract

The corrosive, erosive and/or encrusting effects of a liquid on metal surfaces are monitored by immersing a metallic probe into the liquid, and measuring simultaneously both the differential capacitance of the double layer between the probe and the liquid and the resistance between the probe and an auxiliary electrode, which are representative of the surface condition of the probe.
