“…The calculated equilibrium constants for adsorption ( K ads ) of pyridine thiol onto brass surface is 1.28 × 10 5 L/mol. From the equilibrium constant, Gibbs free energy of adsorption process (∆G o ads ) was calculated using following equation [ 13 , 14 , 15 , 23 , 24 , 25 , 26 , 27 ]. ∆G o ads = − RT ln (55.5 K ads ) where R is the ideal gas constant, T is the absolute temperature and 55.5 is the concentration of water in solution [ 15 ].…”

“…Generally, acids have been applied as pickling solutions with sulfuric acid one of the most common. During the pickling process, the brass surface is prone to damage by corrosion initiated in highly acidic environments [ 10 , 12 , 13 , 14 , 15 ]. When reacted with corrosive media, zinc tends to dissolve into the bulk solution and this process is known as dezincification [ 16 , 17 ].…”

In this study, the inhibitive performance of pyridine-2-thiol added to a corrosive solution was investigated for brass using potentiodynamic polarization, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy. Electrochemical experiments were performed with different inhibitor concentrations in 0.5 M H2SO4 as the corrosive medium. For potentiodynamic polarization, icorr values decreased significantly for the inhibited solutions in contrast with the uninhibited solution. Pyridine-2-thiol had an optimum inhibition concentration of 0.25 mM, giving an icorr value of 1.8 µA/cm2 compared to 26 µA/cm2 for the blank solution. EIS data indicated that Rp and Rct values increased substantially after the addition of the corrosion inhibitor and corrosion inhibition efficiencies of more than 85% was achieved for the majority of the inhibited solutions. Scanning electron microscopy showed defect free and less scale formation for the inhibited surface but the bare brass surface had larger amounts of scale formation. X-ray photoelectron spectroscopy and UV-vis spectroscopy was used to investigate surface chemical composition and inhibitor structural changes over time.

“…However, the application of EDTA-ZnNa 2 as a corrosion inhibitor for metal has hardly been reported. Another organic salt sodium gluconate (C 6 H 11 NaO 7 , Figure 1b) has been applied as a green corrosion inhibitor for iron and steel alloys, [30,31] aluminum alloy, [32] and brass, [33] but also there is almost no report about using it as a corrosion inhibitor for pure Mg.…”

The corrosion inhibiting performance of EDTA‐ZnNa2 and C6H11NaO7 for pure magnesium in a 3.5 wt% NaCl electrolyte was investigated through electrochemical tests and surface microanalysis. And their effect on discharge behavior of Mg anode used for air battery was evaluated through constant‐current discharging tests. The inhibition performance varied with different additive concentrations and the maximum inhibition efficiency values were obtained as 87.11% and 77.70% by using 0.005 M EDTA‐ZnNa2 and 0.01 M C6H11NaO7, respectively. Both the presence of 0.005 M EDTA‐ZnNa2 and 0.01 M C6H11NaO7 in electrolyte improved the battery performance, especially under a smaller discharging current. The discharge platform time was extended from 15.66 to 22.57 h and 20.04 h by adding EDTA‐ZnNa2 and C6H11NaO7 at discharging current density of 2 mA cm−2 respectively, accompanied by a negligible battery voltage drop of about 20 mV. In the case of EDTA‐ZnNa2, zinc hydroxide formed by the dissociated zinc ions cooperated with magnesium hydroxide and organic adsorption film for corrosion inhibition. Therefore, by using it a more pronounced discharge performance was achieved than C6H11NaO7.
