The stability of localized corrosion
Corrosion Science, 1995Abstract Chloride pitting of iron group metals at noble potentials proceeds in the polishing state dissolution, provided that metal chloride in the pit solution is maintained above a critical concentration. It ceases to progress by pit repassivation if the pit is smaller than a critical size, or transforms into the active state pitting if the pit ...

Quantitative Analysis of Localized Corrosion in the Presence of Corrosion Inhibitors
CORROSION 2007, 2007Abstract Field experience suggests that localized corrosion is the major cause of failures in oil and gas production facilities. Significant efforts are currently being directed toward the development of reliable laboratory protocols as well as field corrosion monitoring techniques that will allow the evaluation of the performance of ...

Control of Localized Corrosion Using Green Corrosion Inhibitors
CORROSION 2005, 2005Abstract Green corrosion inhibitors have been developed to minimize environmental impacts. The first requirement of green chemicals is to pass pre-screening based on the criteria of Harmonised Mandatory Control Scheme. In addition, a green chemical should have a Hazard Quotient value of less than 1 for the UK sector; whereas in Norway, a

Predicting Localized Corrosion in Seawater
Corrosion, 2004A number of alloys, including stainless steels, aluminum, and nickel-based alloys, are used in seawater for various applications. The localized corrosion of these materials is affected, among other factors, by temperature, microbial activity, chlorination, and flow rate.

Localized Corrosion in Multiphase Pipelines
CORROSION 2004, 2004Abstract Measurements of the localized flow patterns, flow characteristics, and corrosion rates using high-precision, non-intrusive flow and corrosion/erosion ultrasound system have been made at various locations along the field pipeline. The field pipeline is schedule 40, a 20 cm diameter, multiphase carbon steel flowline

Localized corrosion and crack initiation
Materials Science and Engineering: A, 1988Abstract Consideration is given to the initiation of stress corrosion cracks at metal surfaces where structural features, such as grain boundaries or slip steps, emerge, as well as to initiation from pits, crevices or other geometrical discontinuities, in the context of a variety of metal-environment systems.
