30 Ιουν 2021 · The early presence of sulfate ions in a saturated calcium hydroxide solution was shown to affect the corrosion behavior of the steel. The higher sulfate ion concentrations resulted in the increase of the anodic current exchange density.
22 Απρ 2022 · These ions do not cause corrosion problems in prestressed steel. In alkaline media and in the presence of carbonates, the most common corrosion product is hydrozincite (Zn 5 (CO 3) 2 (OH) 6) [13, 14], and in the presence of sulfates, zinc hydroxysulfate (Zn 4 (SO 4) (OH) 6 · 3H 2 O).
15 Αυγ 2023 · The elevated corrosion rates of the galvanized steel in the alkaline sulfate solutions demonstrated that the early corrosion failures of galvanized PT components can be attributed to the deficient grout that contained high sulfate ion concentrations.
1 Νοε 2018 · Results reveal that the dominant corrosion process of 316 L SS in molten FLiNaK salt is the selective dissolution of Cr from the alloy into the salt. The SO 42− in FLiNaK salt acts as an effective oxidant and accelerates the corrosion of 316 L SS dramatically.
1 Ιουλ 2024 · The chemcial reaction rate of the metal atoms is directly proportional to the concentration of SO 42− ions. The corrosion rate of 316H SS in salt with 1000 ppm SO 42− (167 μm/year) was more than 10 times that in without SO 42− (13.3 μm/year), increasing linearly with increasing SO 42− concentration.
20 Μαρ 2023 · The effect of sulfate ions on localized steel corrosion such as that observed in deficient cementitious grouts in posttensioned bridge construction was assessed by the electrochemical noise...
