... composition, and volume, as well as the effect of galvanic coupling with a SS316 cathode. Results indicate that fissure depth increases with an increase in K₂S₂O₈ concentration but does not progress further after 24–48 hours of exposure in the chemical, or freely-corroding, exposure test. In contrast...

...David A. Dukeman; Christopher L. Alexander There has been concern that prestressing structural steel contained within galvanized bridge tendon ducts may become embrittled due to excessive galvanic coupling with the duct which may be exacerbated by deficiencies within the grout fill. This work...

...Jhon E. Torres-Ramírez; Gustavo S. Duffó; Silvia B. Farina This investigation is a first step in the development of a simple sensor to be embedded in concrete structures to measure the corrosion rate of reinforcement steel (rebars) based on the principle of galvanic couple. To that end, suitability...

...⁾ It is interesting to note that these galvanic couple relationships hold under the acidified and near-neutral electrolytes tested and may not be qualitatively or quantitatively similar in other environments. Figure 19 reports the OCP, anodic and cathodic polarization behavior in an aerated condition in two...

... best, followed by the cathodic protection and inhibitor mechanisms. Overall, these findings suggest that primer quality was the most relevant parameter. Primer application not only decreased the corrosion rate of repaired zones, but also the galvanic couple, which apparently only lasted a few days...

...A.M. Al-Mayouf; N.A. Al-Mobarak; A.A. Al-Swayih The effect of the galvanic coupling between magnetite and iron on their dissolution was investigated in aqueous solutions containing ethylenediaminetetraacetic acid (EDTA) in the presence and absence of ferrous ion, in which magnetite dissolved...

... techniques were investigated. Results for painted zinc and aluminum-zinc alloy coated steel surfaces showed corrosion occurred initially at localized sites on the exposed zinc in both dilute chloride and sulfate solutions and when zinc was galvanically coupled to or isolated from steel. Current density...

...C. M. Mustafa; S. M. Shahinoor Islam Dulal The use of molybdate (MoO₄²⁻) and nitrite (NO₂⁻) as corrosion inhibitors for mild steel galvanically coupled to copper was investigated. In simulated cooling water (SCW), galvanic contact of copper is harmful...
