  5. 5. Corrosion and Surface Studies of Stainless Steel and Chromium Carbide Thin-Films

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonas Högström; Uppsala universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; corrosion; electrochemistry; thin film; stainless steel; passive film; chromium carbide; carbon oxidation; surface; depth profile; XPS; SEM; EQCM; sputtering;

    Sammanfattning : Although the passive films that form on stainless steels have been extensively studied, the concentration depth profiles are not fully understood. Their thinness makes passive films hard to study, but angle-resolved X-ray photoelectron spectroscopy (ARXPS) is a non-destructive technique that can be used to obtain depth information. LÄS MER
