Effects of γ-radiation versus H2O2 on carbon steel corrosion

Radiation Induced Corrosion of Nuclear Fuel and Materials

“…The effect of IR on carbon steel corrosion as an important materials issue in nuclear reactors was investigated (Daub et al, 2010) at pH 10.6. The effect of gamma-radiation on corrosion kinetics was compared with that of chemically added H 2 O 2 , which is considered to be the key radiolytically produced oxidant at room temperature (see section 2.1 for details on its formation).…”

“…Another species such as H 2 O 2 and product of its radiation decomposition-HO 2 radicals are also strong oxidizing agents (Ferradini and Jay-Gerin, 2000;Daub et al, 2010 …”

“…Thus, in many studies, the complicated alpha irradiation is substituted by adding hydrogen peroxide to aqueous solution, because similar behavior of corroding material may be expected (e.g. Daub et al, 2010).…”

Mass and Charge Balance (MCB) Model Simulations of Current, Oxide Growth and Dissolution during Corrosion of Co-Cr Alloy Stellite-6

“…The nature of oxide and the oxide layer structure can also change with time as corrosion progresses even under potentiostatic polarization or constant solution conditions. [8][9][10][12][13][14][15][16][17] The type of oxide that can form and its rate of formation depend on solution environmental parameters such as pH, temperature and the concentrations of redox active species. Few existing models specifically incorporate the solution environment in their model parameters and, even in those models that do so, the effects are formulated primarily based on empirical relationships.…”

“…Alloys owe their corrosion resistance to protective oxide films formed on their surfaces. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Corrosion involves surface redox reactions (metal oxidation coupled with solution reduction) and interfacial transfer of the charged species involved in the redox reactions. The presence of an oxide film hinders the interfacial charge transfer, slowing the rate of corrosion.…”
