Der Einfluß von Kupfer auf das Korrosions‐ und Passivierungsverhalten von Eisen‐Chrom‐Legierungen Teil II: Oberflächenanalytische Untersuchungen

Abstract: Es wurden potentiostatisch in I N H2S04 erzeugte bzw. einer Ausschaltaktivierung unterworfene Passivschichten von reinen FeCr-Legierungen mit 7 bzw. 11% Chrom sowie solchen mit je 1% Kupfer mit XPS-Analyse und XPS-Drehwinkelexperimenten untersucht. Nach einstundiger Passivierung wurden Schichtdicken von 1 bis 4 nm erhalten. In Ubereinstimmung mit den fruher bestimmten Schichtbildungsstromen wird die Schichtdicke durch Kupfer erhoht und durch hohere Chromgehalte verringert. Die unmittelbar nach der Selbstaktivi… Show more

“…[1][2][3] It has been well known that the addition of copper (Cu) to ferritic, austenitic or duplex steels improves the resistance to uniform corrosion in sulfuric media. [4][5][6][7][8] It was reported in the previous studies that the mechanism on the beneficial effect of Cu addition on the steels is based on the suppression of anodic dissolution by elemental Cu deposition on the corroded surface of stainless steels. 9) In acid chloride media, the studies of redeposited metallic copper have been conducted due to the presence of Cl À ions.…”
