✦ Synopsis


This paper summarizes the results obtained in the MICAT project for mild steel specimens exposed for 1 to 4 years in 47 marine atmospheres in the Ibero-American region. All these atmospheres were characterized for climatology, pollution and corrosion rates according to ISO standards. Complementary morphological and chemical characterization of the steel corrosion product layers (SCPLs) formed in these atmospheres was carried out. The overall analysis of results contributes to understanding, in a systematic way, how atmospheric corrosivity categories can be correlated with corrosion mechanisms. Special aspects of the atmospheres, from pure to mixed marine, were considered.

Die Arbeit fasst die Ergebnisse zusammen, die in dem MICAT Projekt fu Èr unlegierte Stahlproben, die 1 bis 4 Jahre in 47 Meeresbzw. Ku Èstenatmospha Èren in der Ibero-Amerikanischen Region ausgelagert waren, erhalten wurden. Alle diese Atmospha Èren wurden entsprechend den ISO Normen im Hinblick auf klimatische Verha Èltnisse, Luftverunreinigung und Korrosionsgeschwindigkeiten charakterisiert. Zusa Ètzlich erfolgte eine chemische und morphologische Charakterisierung der sich in diesen Atmospha Èren gebildeten Stahlkorrosionsproduktschichten. Die allgemeine Analyse der Ergebnisse tra Ègt in einer systematischen Art und Weise zum Versta Èndnis bei, wie die atmospha Èrischen Korrosionskategorien mit dem Korrosionsmechanismus korreliert werden ko Ènnen. Spezielle Aspekte der Atmospha Èren, von reinen zu gemischten Atmospha Èren, wurden beru Ècksichtigt.
