In-situ electrochemical impedance measurement of oxide film on 304 SS in 288 C water

Conference ·
OSTI ID:20002544
The electrical resistivity of the oxide film formed on 304 stainless steel (SS) in 288 C water was evaluated by an in-situ AC impedance measurement. The higher electrochemical corrosion potential (ECP) was measured in the presence of hydrogen peroxide (H{sub 2}O{sub 2}) than oxygen (O{sub 2}), and the polarization resistance decreased with increases in ECP and H{sub 2}O{sub 2} concentration. The impedance data suggested that a less resistive oxide was produced when H{sub 2}O{sub 2} was present in water.
