2002 (English)In: Corrosion Science, ISSN 0010-938X, E-ISSN 1879-0496, Vol. 44, no 10, 2253-2270 p.Article in journal (Refereed) Published
A mechanism for metal dusting of chromia-forming stainless steels is proposed, based on results from laboratory exposures of 304L stainless steel at 650 degreesC for 1000 h in a synthesis gas low in water vapour, 25%CO + 3%H2O + H. The work focuses on the role of carbides and oxygen to explain the different corrosion mechanisms and give a description of the metal dusting phenomenon as it appears in engineering alloys. Metallographical examinations, FEG-SEM, SEM-EDX analysis and X-ray diffraction, as well as thermodynamic calculations were made in order to identify the proposed metal dusting mechanism.
