Abstract
To study the mechanism of the corrosion process and to control the corrosion process in relation to the radwaste management, passive films on the metal surfaces and corrosion of iron, carbon steel, and titanium have been studied. Total charges for passivation, breakdown and repassivation process were measured and compared to understand the characteristics of passive films including the growth rate and the stability of the passive films. The bigger the charges for passivation process, the more metal dissolution and corrosion attack were observed. Increasing the concentration of chloride ions, the rate of coverage of exposed metal became slower and the stability of passive fimes were weakened. Corrosion measurements of iron, carbon steel, and titanium were performed. Iron and carbon steels were proven to become passivated in the carbonate media, but pitting corrosion occurred in the presence of chloride ions. From the impedance data, we conclude that an adsorptive reaction forming Fe(OH){sub 2} occurs in the dissolution of iron and carbon steel. In 0.1 M NaHC0{sub 3} solution, iron and carbon steel showed a corrosion rate of 43-61 {mu}m/yr and 18 {mu}m/yr, respectively. In ground water, iron showed a corrosion rate of 5.8{mu}m/yr and carbon steel showed an even smaller corrosion
