Effect of cation type of chloride salts on corrosion behaviour of steel in concrete powder electrolyte solution in the presence of corrosion inhibitors

Effects of NH4+, Na+, and Mg2+ ions on the corrosion behavior of galvanized steel in wet–dry cyclic conditions

“…However, the effects of these cations on GS corrosion are less researched. [25][26][27] It is believed that cation does not take part in the mechanistic corrosion pathway of corrosion reactions directly. Instead, it alters the properties of the system being studied, such as the electrical double layer, electrochemical potential, and pH value, which affects the corrosion rate and the corrosion mechanism.…”

“…Instead, it alters the properties of the system being studied, such as the electrical double layer, electrochemical potential, and pH value, which affects the corrosion rate and the corrosion mechanism. [25][26][27] In contrast, the anions present in the electrolyte have been reported to influence the atmospheric corrosion mechanism involving anodic reaction remarkably. The influence of cations on atmospheric corrosion has been overlooked, and the corrosion rate of metals is generally associated only with the amount of chloride and sulfate ions on the surface.…”

Kalıp Şartlandırıcı Serpantinde Oluşan Korozyonun İnhibitör Kullanımıyla Engellenmesi

“…A. Wachter'ın 1945 yılındaki çalışmasından iki yıl sonra ürün ABD'deki benzin boru hatlarının üçte birinden fazlasında kullanılmıştır [21]. NaNO2 sulu ortamda korozyon inhibitörü olarak başarıyla kullanılmaktadır [22]- [24]. Belirgin inhibisyon için ihtiyaç duyulan NaNO2, koşullara, suyun pH ve bileşimine göre değişmektedir.…”

Effects of Transverse Crack on Chloride Ions Diffusion and Steel Bars Corrosion Behavior in Concrete under Electric Acceleration

“…To extend the service life of marine reinforced concrete structures, the utilized steel bars are often protected by increasing the thickness of the concrete cover which prolongs the ion transportation distance and provides a high alkalinity environment, which forms a thin oxide film on the steel surface [6]. However, due to the effect of load and the inherent defects of concrete itself, many micro-cracks emerge in the concrete cover.…”

“…However, due to the effect of load and the inherent defects of concrete itself, many micro-cracks emerge in the concrete cover. Transverse cracks are the most common form of cracks in reinforced concrete structures, and are primarily caused by shrinkage [6], chemical reaction [7], weather processes (e.g., freezing and thawing) [8], and mechanical loading [9]. These cracks provide direct channels for chloride ions and oxygen to enter the concrete structure, thus greatly increasing the risk of corrosion damage to the reinforced concrete structure [10,11,12,13].…”
