Various Forms of Localised Corrosion in Iron and Steel: Common Features and Differences

Abstract

Various factors affecting the nucleation and development of corrosion pits, crevices and stress corrosion cracks in iron and steel are reviewed for the purpose of assessing the presumed correlation between pitting corrosion (PC), crevice corrosion (CC) and stress corrosion cracking (SCC) phenomena. Similarities and differences are emphasised and discussed. Some tentative recommendations for future research are given. In an appendix, some aspects of hydrogen embrittlement (HE) are reviewed in connection with the phenomena of localised corrosion (LC).
