In situ synchrotron X-ray micro-tomography study of pitting corrosion in stainless steel


Ghahari, S M; Davenport, A J; Rayment, T; Suter, T; Tinnes, J P; Padovani, C; Hammons, J A; Stampanoni, M; Marone, F; Mokso, R (2011). In situ synchrotron X-ray micro-tomography study of pitting corrosion in stainless steel. Corrosion Science, 53(9):2684-2687.

Abstract

Pitting corrosion of stainless steel has been investigated with high-resolution in situ X-ray microtomography. The growth of pits at the tip of stainless steel pins has been observed with 3D microtomography under different conditions of applied current and cell potential. The results demonstrate how pits evolve in stainless steel, forming a characteristic “lacy” cover of perforated metal. In addition, it is shown how the shape of pits becomes modified by MnS inclusions.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
