20.500.12556/DiRROS-23437 Effect of sulfide in a 0.2 M NaCl solution on copper and pre-oxidized copper in oxic conditions This study investigated copper and pre-oxidized copper immersed in 0.2 M NaCl solutions containing different concentrations of sulfide ions. In order to investigate the corrosion processes, the corrosion potential and electrochemical impedance at room temperature and at an elevated temperature were measured for 24 h during and after exposure to the chloride solution with different sulfide concentrations in aerated conditions. The surfaces of the pre-oxidized copper were characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy (EDS), a focused ion beam scanning electron microscopy (FIB-SEM), and Raman spectroscopy. It was shown that the concentration of sulfide ions in the chloride environments, in addition to the temperature itself, greatly affect the film formation in oxic conditions. The thickness of the films observed corresponds well to those calculated using cathodic stripping voltammetry. The mechanism of corroding copper in chloride/sulfide system was proposed. copper pre-oxidized copper chloride and sulfide environment electrochemical properties surface characterization Raman cyclic voltammetry baker predoksidiran baker kloridno in sulfidno okolje elektrokemijske lastnosti površinska karakterizacija Raman ciklična voltametrija true false true Elsevier Angleški jezik Slovenski jezik © 2025 The Authors Neznano 2025-08-29 13:42:28 2025-08-29 13:46:48 2025-10-24 03:54:21 0000-00-00 00:00:00 2025 0 0 str. 1-18 [article no.] 107387 Vol. 72 Sep. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-08-08 544.5/.6 2468-0230 10.1016/j.surfin.2025.107387 246736643 https://doi.org/10.1016/j.surfin.2025.107387 0 3e8918b7-84cd-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34653 RAZ_Prijatelj_Klara_2025.pdf RAZ_Prijatelj_Klara_2025.pdf 1 2E4A194DEFA52D1C88C24E5EBA07659C 4c9812b2881c3a2ec7a46839e608760aba8c2d4d852b743d30a52604dc2aec77 c20c18c7-84cd-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34655 http://hdl.handle.net/20.500.12556/DiRROS-23268 0 d4f40112-84cd-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34656 Zavod za gradbeništvo Slovenije Dataset for the article Effect of sulfide in a 0.2 M NaCl solution on copper and pre-oxidized copper in oxic conditions 0 0 0
