20.500.12556/DiRROS-20212 Monitoring copper corrosion in bentonite by means of a coupled multi-electrode array This work focuses in monitoring the corrosion processes on copper in a slightly saline environment under oxic conditions, which simulated the first part of high-radioactive waste disposal in bentonite. Besides coupled multi-electrode arrays (CMEA), also electrochemical impedance spectroscopy measurements were implemented. It was expected that this combination of methods would define the general corrosion rate, as well as the spatio-temporal evolution of anodic and cathodic processes. Anodic currents measured by CMEA showed that the corrosion rates decreased with time. Since maximum anodic activity switched between the electrodes, this situation was not individually valid for all the electrodes. At the end of exposure, different spectroscopic techniques were applied in order to identify the modes of corrosion and types of corrosion products. Uneven general corrosion without evident pits was indicated. copper bentonite saline groundwater coupled multi electrode array corrosion materiali baker bentonit slana podtalnica sklopljena mreža elektrod korozija true false true Maney for the Institute of Materials, Minerals, and Mining Angleški jezik Slovenski jezik © 2017 The Author(s) Neznano 2024-08-14 13:19:51 2024-08-14 13:42:48 2024-08-16 03:57:23 0000-00-00 00:00:00 2017 0 0 str. 70-77 suppl. 1 Vol. 52 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2017-08-23 620.1/.2 1743-2782 10.1080/1478422X.2017.1312200 2315623 http://www.tandfonline.com/doi/full/10.1080/1478422X.2017.1312200 Odprti dostop 1 62389873-5a1e-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28298 RAZ_Kosec_Tadeja_2017.pdf RAZ_Kosec_Tadeja_2017.pdf 1 8758773B2BFD53939641B498640786E8 1ad1ec110f7c30b2e10bf3782b08962f1c7c99d342f3d1aa57ad881a1b1c674c 87bac87b-5a21-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28299 Zavod za gradbeništvo Slovenije 0 0 0
