Journal ArticleDOI
A new microelectrochemical method to study pit initiation on stainless steels
TL;DR: The results obtained from stainless steels indicate that MnS-inclusions, acting as potential nucleation sites for pitting corrosion, are dissolved even in chloride-free solutions, whereas stable pit growth only occurs in the presence of chlorides as discussed by the authors.
Journal ArticleDOI
Micro- and nanotechniques to study localized corrosion
H. Böhni,T. Suter,A. Schreyer +2 more
TL;DR: In this article, the authors used microelectrochemical methods and scanning tunneling microscopy (STM) to study localized corrosion processes on passive metals in the μm-and nm-range.
Journal ArticleDOI
Microelectrodes for corrosion studies in microsystems
TL;DR: In this paper, the microcapillary technique is used to study the corrosion behavior of micro-systems and results obtained from studies of localized corrosion processes of stainless steels are presented and discussed.
Journal ArticleDOI
Metastable Pitting and Semiconductive Properties of Passive Films
Patrik Schmuki,H. Böhni +1 more
TL;DR: In this article, the photoresponse is determined by the defects in the electronic structure of the films leading to localized states in the bandgap region, and the fewer deep localized states are present, the higher is the resistance of the materials against pitting corrosion.
