Corrosion inhibition of mild steel by ethylamino imidazoline derivative in CO2-saturated solution

Electrochemical Corrosion Behaviour of Pb-free SAC 105 and SAC 305 Solder Alloys: A Comparative Study

“…Nyquist plots are shown in Figure 5 for the solder alloys, where difference in the diameter of the impedance loops for different solder alloys can be observed. Nyquist plots are characterized by a semicircle or capacitive loop from high to low frequencies where these capacitive loops are ascribed to the double layer capacitance and charge transfer resistance (Okafor et al 2009). In this study, the obtained curves are approximated by a single capacitive semicircle which is ascribed to the double layer capacitance and charge transfer resistance (Okafor et al 2009;Raja et al 2013).…”

“…The charge transfer resistance, R ct can be obtained from the semicircle diameter of the Nyquist plot. Capacitance, C dl can be calculated using (1) where the characteristic frequencies f max were obtained from the semicircles maxima (Okafor et al 2009). The electrochemical parameters are shown in Table 2.…”

Electrochemicaland Surface Characterization Studies on C38 Steel in 1 M Hydrochloric Acid Medium Using Prop-2-en-1-One Derivatives as Corrosion Inhibitors.

“…1193 rise inhibition protection, best thermal stability and prevent the odor irritating for alloys and metals in different aggressive solution [17][18][19][20][21][22] . Therefore, the improve of novel adjuster inhibitors include 4-aminoantipyrineheterocyclic ring and the research of the relations among the chemicalstructure of inhibitors and their protection led to the higher significance in theoretical points and industrial.…”

Electrochemicaland Surface Characterization Studies on C38 Steel in 1 M Hydrochloric Acid Medium Using Prop-2-en-1-One Derivatives as Corrosion Inhibitors.

“…Different inquires about uncovered that the influenced of adsorption not only the charge surface and nature of the metal, but also by the chemical assembled of inhibitors. The heterocyclic substances include N atoms, such as 4-aminoantipyrine are good corrosion protective with corrosive solution due to rise inhibition protection, best thermal stability and prevent the odor irritating for alloys and metals in different aggressive solution [17][18][19][20][21][22] . Therefore, the improve of novel adjuster inhibitors include 4-aminoantipyrineheterocyclic ring and the research of the relations among the chemicalstructure of inhibitors and their protection led to the higher significance in theoretical points and industrial.…”
