Corrosion of AISI 4130 Steel Alloy under Hydrodynamic Condition in Ethylene Glycol + Water + NO2− Solution

Investigations on the corrosion of constructional steels in different aqueous and simulated atmospheric environments

“…We obtain time constants close to 0.02, indicating that the equivalent electrical circuits are associated with relatively rapid charge/discharge processes [22,35]. The corrosion parameters found for S235 and S355 steels are not far from those of many steels found in the literature [36][37][38][39][40][41][42].…”

“…In the case of S275 steel, the measured corrosion rate was around 0.007 mm/year only and therefore this material has an excellent resistance against uniform corrosion. It is worthwhile to note that Danaee et al [22] …”

Clays valorization as corrosion inhibitors for E400 reinforcing steel

“…The solution resistance increases due to the formation of a film on the metal surface [37]. The difference between Rs values in the presence and in the absence of inhibitors is attributed to that film.…”

“…We can calculate and compare the time constants once the pure capacitances (C) are known. These can be obtained from the CPE (Q) and the charge-transfer resistance using the following equation [36,37,39]:…”

Performance evaluation of phosphite NaCo(H2PO3)3·H2O as a corrosion inhibitor for aluminum in engine coolant solutions

“…Engine coolant is usually a waterethylene glycol mixture. [7][8][9][10] Corrosion protection by inorganic inhibitors is mostly based on the adsorption of these compounds on the metal surfaces to produce an impervious physical layer which prevents any further corrosion reactions from taking place. [4][5][6] For many years, the application of corrosion inhibitors, such as inorganic inhibitors, has been the most common method for reducing the corrosion of radiators.…”
