“…[1,20,26] Due to the existence of Cl − in the solution, the Cu in the matrix is preferentially dissolved and redeposited to form Cu 2 O, as the reaction process shown in formulae (8) and T A B L E 3 Fitting parameters of electrochemical impedance spectroscopy of 90/10 copper-nickel alloy with different Fe content in 3.5% NaCl solution after corrosion for 1 month (9). [27,28] Cu 2 (OH) 3 Cl is formed by the reaction between thickening Cu 2 O film and adsorbed Cl − , as shown in formula (10). [29] It is revealed in the literature that paratacamite is the most stable of the two isomers of Cu 2 (OH) 3 Cl.…”

“…Cu 2 O is easy to react with Cl − from solution to form Cu 2 (OH) 3 Cl. The reaction process is shown in formulae (8)(9)(10). According to previous studies [34,35] and the point defect model (PDM), Cu 2 O film is a nonstoichiometric P-type semiconductor membrane with lots of cationic vacancies (V′ Cu ).…”

“…The uniformly distributed ZnS formed in the corrosion product film effectively protected the substrate. [10] The addition of the Fe element was also found to improve the corrosion resistance of different types of Cu-Ni alloys through experiments. There is evidence that the corrosion resistance of Cu-Ni alloy can be improved when Fe is dissolved in the alloy.…”

“…This affects the properties of the alloy, such as mechanics and corrosion, and it is of high research value to enhance the corrosion resistance of the alloy by adding corrosion-resistant elements. [7][8][9] Tandon et al [10] investigated the effect of Zn element addition on the corrosion resistance of Cu-Ni alloys in seawater containing S 2− ions. After corrosion experiments, it was concluded that the corrosion rate of Cu-Ni alloys with Zn element addition was reduced due to the strong resistivity of Zn element to elevated sulfide compared to other elements.…”

The effect of Fe/Mn content on the metallographic structure, mechanical properties, and corrosion resistance of 90/10 copper–nickel alloy using electrochemical methods, scanning electron microscope, energy dispersive spectroscopy, X‐ray photoelectron spectroscopy, Tafel experiments, and electrochemical impedance spectroscopy measurements were investigated in this paper. The experimental results indicated that the tensile strength of the alloys increases from 326 to 347 MPa with the change of Fe/Mn content, the yield strength of 90/10 copper–nickel alloys is approximately 150 MPa, and the elongation of the alloys was reduced from 51% to 37%. Moreover, as corrosion proceeds, the corrosion product film was mainly composed of Cu2O, Cu2(OH)3Cl. In addition, the Cu–10Ni alloy with Fe/Mn content of 1.69/0.69 has good corrosion resistance properties.

Green tea leaves contain antioxidant compounds that can be used as organic inhibitors in a corrosion process. Tea leaves were extracted by maceration method using 70% ethanol solution with a solid:solvent ratio of 1:8 (w/v) for 1 x 24 hours in an atmospheric room. The extract was then concentrated with a rotary evaporator and separated with solvent under vacuum conditions at 852 mbar, temperature of 70oC and rotation of 80 rpm. The results of the qualitative test of extra tea leaves using 10% NaOH and 1% FeCl3 changed the color to brownish orange and blue-black. This indicates the content of flavonoids and tannins. Green tea leaf extract is also applied to control the corrosion rate of brass metal. Variations in the concentration of tea leaves were 200, 400, 600 ppm in 3.56% NaCl solution. The pump circulation is carried out for 40 hours, the weight loss method is carried out every 8 hours. The average corrosion rate without inhibitor is 3.95 mmpy, the corrosion rate with 200 ppm inhibitor is 1.24 mmpy, the corrosion rate with 400 ppm inhibitor is 0.46 mmpy, the corrosion rate with 600 ppm inhibitor is 0.23 mmpy. A significant decrease in the corrosion rate occurred at a concentration of 600 ppm with an efficiency of 92.32%.
