Gamma-radiation-induced corrosion of carbon steel in neutral and mildly basic water at 150 °C

Radiation Induced Corrosion of Nuclear Fuel and Materials

“…On the other hand, the amount of corrosion products in an irradiated system depends on the temperature and on the dose; other compounds present in water affected the total amount of corrosion products only marginally. In the solid phase formed during contact with deionized water, the predominant crystalline corrosion products were magnetite and lepidocrocite, which is in agreement with (Smart et al, 2008) and partially (Daub et al, 2011). Other published studies discussed here dealing with water-steel system and providing data on various corrosion parameters (e.g.…”

“…In the work of Daub et al (2011), the effect of gamma-radiation on the kinetics of carbon steel corrosion has been investigated by characterizing the oxide films formed on steel coupons at 150 °C in aqueous solutions and at two pH values. Though variations in system temperature and pH may affect rates of oxide film growth and dissolution, they do not play a significant role in determining the chemical composition of the oxide film.…”

Estimation of the Behaviors of Selenium in the Near Field of Repository

“…-, H•, H2 and H + produced by the water radiolysis [32] will contribute to make less oxidized iron compounds. However, higher oxidized corrosion products can also be formed by oxygen in the groundwater and •OH, O2 and H2O2 as water radiolysis products, and they will hardly capture the selenite or selenide in a nuclear repository.…”

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.…”
