    Mineralogiczno-geochemiczna charakterystyka produktów korozji żelaza z Kopalni Soli »Wieliczka«
    (Wydawnictwa AGH, 2010) Malinowski, Łukasz; Sawłowicz, Zbigniew; Przybyło, Jerzy
    Corrosion is a process of physico-chemical destruction of metals under the influence of surrounding environment. In a salt mine, where the salinity of air and water is high, the destruction is very fast and efficient. Metal fragments (pipes, chain), at different progress of corrosion, were collected underground in the Wieliczka Salt Mine. Two main layers of corrosion were distinguished (external »A« and internal »B«), each of them was further subdivided into two sublayers. In addition, black blebs, present on the surface of different metal fragments, were studied. XRD determinations showed that the studied layers were composed of different amounts of: akaganeite, hematite, goethite, halite, magnetite, and subordinate amounts of lepidocrockite. The mineral composition greatly affects the color of the layers. SEM-EDS studies revealed various morphological forms of different chemical composition.
