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. (C) 2011 Elsevier Ltd. All rights reserved.
