determining factors for Anodic Polarization curves of typical structural materials of boiling water reactors in high temperature high purity water
Journal of Nuclear Science and Technology, 2012Co-Authors: Masahiko Tachibana, Kazushige Ishida, Ryosuke Shimizu, Yoichi Wada, Nobuyoshi HaraAbstract:In order to examine the Anodic Polarization characteristics of typical structural materials of boiling water reactors (BWRs), the Anodic Polarization curves of type 316L stainless steel (316L SS) and Alloy 182 were measured in deaerated high purity water at 553 K using the previously reported measurement method which was confirmed suitable for high temperature – high purity water. In order to specify which constituent element determines the dissolution characteristics of these materials, the Anodic Polarization curves of pure iron, pure nickel, and pure chromium were also surveyed. The Anodic Polarization curve of 316L SS was determined to have active, passive, and transpassive states which were the same as type 304 SS (304 SS) showed. But, Alloy 182 had different Polarization characteristics especially near the corrosion potential as it had no active state. From comparison results of the Polarization characteristics of these materials and their constituent elements, the corrosion characteristics of these...

Corrosion evolution and stress corrosion cracking of E690 steel for marine construction in artificial seawater under potentiostatic Anodic Polarization
Construction and Building Materials, 2020Co-Authors: Liwei Wang, Juncheng Xin, Huiyun Tian, Xin Wang, Zhongyu CuiAbstract:Abstract In the present work, corrosion evolution and stress corrosion cracking behavior of E690 steel for marine equipment and construction under potentiostatic Anodic Polarization are investigated via electrochemical analysis, morphology and topography observation and slow strain rate tensile tests. Positive shift of Anodic potential accelerates the two dissolution stages including electrochemical oxidation from Fe to Fe2+ and Fe2+ to Fe3+ of E690 steel. Composition of corrosion products is not altered by Anodic Polarization but the rust layer morphology and structure are changed. Pitting corrosion initiated around complex oxide inclusions and its transformation to uniform corrosion dominates the corrosion evolution process at OCP, while local acidification induced corrosion pits beneath thick and cracked rust layer dominates the localized corrosion under strong Anodic Polarization. The SCC susceptibility of E690 steel increases with the positive shift of applied Anodic potentials, attributed to the acceleration of Anodic dissolution (AD) effect under weak Anodic Polarization and synergistic effect of AD and hydrogen embrittlement (HE) under strong Anodic Polarization.
