Corrosion of Mild Steel in low Conductive Media simulating Natural Waters.
Résumé
The corrosion of a mild steel was examined in two aerated neutral aqueous solutions, defined as reference solution (0.2 g L−1NaCl) and as Σ-solution (1.3 g L−1NaCl + 0.63 g L−1NaHCO3 + 0.27 g L−1Na2SO4). Their composition was chosen on the basis of the physical and chemical properties of certain natural waters. The solutions simulated the least (reference solution) and the most (Σ-solution) aggressive waters of the Sebou river in Morocco, as determined after a four-year examination (1991–94), at 13 pump stations located along the river.
