Corrosion takes place without an FeCO/sub 3/ corrosion film if the Fe/sup 2+/ ions in the water are in the solubility range. The corrosion rate increases proportionally with CO/sub 2/ partial pressures to a power of about 0.7. The amount of Fe/sup 2+/ corrosion products in the water is equally as important as the CO/sub 2/ level. Low concentrations of Fe/sup 2+/ and high CO/sub 2/ levels can lead to rapid corrosion. When the amount of Fe/sup 2+/ exceeds the solubility limit, corrosion films tend to form. Such conditions led to much lower corrosion rates than for solutions with very low amounts of Fe/sup 2+/. Flow-induced mesa attack can occur in water saturated with FeCO/sub 3/ under turbulent flow conditions where film formation is prevented locally.
