Preface
The Pitting corrosion book covers recent research challenges and various
accomplishments in the field of corrosion. The book is a proven record of excellent
scientific achievements in the field of pitting corrosion.
Pitting corrosion involves local dissolution followed by the formation of cavities on
metals surfaces coated with a passive film, when exposed to an aqueous solution
containing aggressive anions, such as chloride and sulfate. Pitting is one of the most
destructive forms of corrosion, as it causes potential failure of metals and alloys due to
perforation/penetration. Pitting corrosion can be quite small on the surface and very
large on the subsurface. The process consists of various stages including passive film
breakdown, metastable attack, stable growth and pit stifling or death. The breakdown
of the passive film is required for pits to initiate. The metastable pitting phase can be
considered as a key stage of pitting corrosion, since only pits that continue to grow
become stable growing pits. Pitting is influenced by metal composition, electrode
potential, temperature, surface condition, and environmental parameters such as
aggressive ion concentration, pH, and inhibitor concentration.
Accurate and efficient detection and monitoring of pitting corrosion is very
challenging. Pitting failures can occur unexpectedly, and with minimal overall metal
loss. The monitoring of pitting corrosion can be further complicated by a distinction
between the initiation and propagation phases of pitting processes. Developing and
understanding the mechanisms by which pits form and propagate may allow
engineers to build more accurate corrosion models in order to predict the lifetime of
components and, thus plan when inspection and replacement are needed.
The first chapter addresses the electrochemical characterization of pitting corrosion
with an emphasis on the behavior of beryllium using single and poly crystalline scales
under different conditions, such as the presence of chloride, using SEM examination
techniques. The second chapter discusses the general mechanisms of pit growth
during pitting corrosion in general, using Al and Al alloys as examples while focusing
on pitting morphology, pit propagation, and hydrogen evolution results.
