“…The measurement of the amount of products generation or reactants loss is a convenient method for determining the rate of galvanic corrosion [34]. In this study, the measurement of hydrogen generation is preferred over weight loss measurement due to possible errors in iron oxides precipitation.…”

“…Thus, the problem of galvanic interaction betweeni the ferritic and austenitic phases must be solved by superposition of all the relevant polarization curves. Davies et al 7 propose a more general model taking into account both anodic and cathodic reactions occurring on both metal surfaces in order to describe the galvanic action between different stainless steels. At the galvanic potential (which corresponds to the corrosion potential of the duplex steel) charge neutrality and uniform potential distribution over both metal surfaces are assumed.…”

This investigation has concerned the active dissolution of a duplex stainless steel in two different acidic solutions together with a comparison of the active dissolution of the corresponding aand 'y-phases in order to establish the type of interaction between the phases. In the two acid solutions investigated, it becomes clear that galvanic action between the two phases took place, although leading to different types of dissolution.Some other particular features of the active dissolution of duplex steels, such as the time dependence of the anodic current, the influence of surface morphology, surface area ratio, etc., are also discussed.

Galvanic corrosion behavior of TA2/316L composite plate was investigated in the solution of 3.5 wt% NaCl by galvanic potential monitoring, scanning localized electrochemical impedance spectroscopy (LEIS) and scanning vibrating microelectrode (SVME) techniques. The results demonstrated that the pitting corrosion resistance of 316L for the galvanic combination sample is lower, and the coupled current density is higher than for the single 316L sample. It indicates that the galvanic action works on the corrosion behavior of the TA2 titanium alloy/316L stainless steel galvanic combination in sodium chloride solution. The galvanic effect width was determined as 1500 mm.
