... of corrosion and cavitation. To understand the origin of corrosion, extensive water chemistry analysis was performed, which revealed the presence of corrosive species such as sulfate and nitrate ions, presumably from the flue gas, which would have caused pH to drop. Autoclave corrosion tests also revealed...

... of corrosion in amine systems which can have similarly destructive results. This paper will present five case studies of corrosion related failures in alkanolamine acid gas removal systems including examples of the following types of corrosion: Uniform, Pitting, Chloride Induced Crevice, Cavitation...

... ABSTRACT Cavitation conditions using a vibratory cavitation testing were imposed on alloy UNS N10665 in seawater. Free corrosion potentials and mass loss in the presence and absence of cavitation were also determined for this alloy. The cavitation tests were made at a frequency of 20 KHz...

... Abstract UNS S32550 alloy was exposed to cavitation conditions using a vibratory cavitation testing apparatus in seawater. The work also included measurements of free corrosion potentials, and mass loss in the presence and absence of cavitation. The cavitation tests were made at a frequency...

... performance of commercially pure titanium (CP-Ti) and three alloys in two tribo-corrosion situations (1) erosion-corrosion, where the wear is due to impacting solids in a liquid medium and (2) cavitation-corrosion, where the wear is due to impacting micro-jets formed by imploding vapour bubbles. The erosion...

... This paper outlines the development of an ultrasound-based, bench-top test to measure the effectiveness of corrosion inhibitors when subjected to cavitating bubbles. It is proposed that the cavities produced by an ultrasonic probe are analogous to the collapsing bubbles that are found in the mixing region...
