The Effect of oxide film on electrochemical corrosion potential of stainless steel in high temperature water

Sato, Tomonori ; Uchida, Shunsuke; Tsukada, Takashi ; Sato, Yoshiyuki*; Mkel, K.*

measurements of electric resistance and multilateral surface analyses of oxide films on stainless steel specimens exposed to high temperature pure water containing H $_{2}$ O $_{2}$ and O $_{2}$ were carried out to evaluate properties of these oxide films and their effects on ECP. During measurement of electric resistance, the potential of the specimens was kept at a natural potential with regard to the reference electrode to avoid change in oxide properties. The results can be summarized as follows. (1) Major parameters of the electric resistance measurement apparatus could be optimized so as to improve the quality of obtained data. (2) The specific electric resistance of oxide film formed under 100 ppb H $_{2}$ O $_{2}$ exposure at 288 $^{circ}$ C was about 3 Mcm, 150 times higher than under 200 ppb O $_{2}$ exposure. (3) It was confirmed that the effect of potential drop caused by the electric resistance of the oxide film and corrosion current density on ECP was small.
