Abstract

Abstract: Corrosion monitoring station was installed at 'Geotermia Mazowiecka' geothermal plant in Poland. Linear polarisation resistance and electrochemical impedance spectroscopy techniques were applied to estimate the corrosion rate and the surface changes of K55 carbon steel, L80‐13CR and 316 stainless steels directly in the geothermal water flux. The enhanced corrosion of K55 carbon steel and corrosion rate of L80‐13CR and 316 stainless steels was observed. The formation of biofilm increased the resistivity of the surface.
