A potentiodynamic polarization technique has been applied to characterize the corrosion behavior of AISI 316L stainless steel, an iron-based alloy (9Cr-1Mo), a nickel-based alloy (INCONEL/SUP R/ alloy 625), and mild steel ASTM A-36. Corrosion rate was affected greatly by temperature. The pitting potentials decreased with increasing temperature. The nickel-based alloywas resistant to the geothermal water and did not undergo pitting corrosion. All measurements of corrosion--corrosion rate, pit density, maximum pit depth, charge consumed, and polarization resistance--corroborate the decrease in corrosion rate at tested temperatures.
