Abstract
In the previous report, it was found that the corrosion rates measured by cell voltage-current curves were in good agreement with those found by weight loss measurements at the stagnant condition, if the sweep velocity of cell voltage was less than 100mV/min and the area ratio of cathode to anode was more than 1.
In this report, cell voltage-current curves were measured under the condition that the sweep velocity of cell voltage was 100mV/min and the area ratio of cathode to anode was 1.
In the first time, the effects of the concentration of chloride ion and flow rate on corrosion rates of mild steel were investigated in 0.3-30g/l sodium chloride solution recycling at the rate of 0-2m/sec at 20-22°C.
Then, corrosion rates of mild steel in the industrial waters at Kawasaki City were measured, and it was indicated that their corrosion rates in these waters were greatly affected by two factors: concentration of chloride ion and flow rate.
