“…Rodrigues et al reported that Al possessed the lowest I corr of 1.59 × 10 –7 A cm –2 in neutral NaCl solution rather than in acid and alkaline solutions and the antierosion of Al could be improved through adding tannin in the solutions. It was also reported that the steel and copper exhibited higher anticorrosion performance in HCl solution with higher concentrations of 2-ethyl phenyl-2, 5-dithiohydrazodicarbonamide. However, the electrolyte solution characteristics are not considered in the conventional models for the prediction of corrosion, and thus it cannot accurately predict the corrosion behaviors of metals. , For example, the predicted I corr values (7.24 × 10 –3 A cm –2 @ pH = 1) of hypereutectic high chromium cast iron were much higher than the measured data (2.57 × 10 –6 A cm –2 @ pH = 1).…”

Proton exchange membrane water electrolysis (PEMWE) is one of the potential strategies to generate green hydrogen energy, and anticorrosive coatings are mandatory to protect the bipolar plates, an important component of PEMWE. However, it is still challenging to explore the high-corrosion-resistance coatings by trial and error. In this paper, the corrosion properties of Ta and its alloys as examples are studied theoretically; in particular, the influences of crystal planes and alloying elements on the corrosion resistance have been studied systematically. Four descriptors, surface energy density ξ, work function τ, electronic descriptor ψ, and d band center ς, are proposed to screen the high-corrosion-resistance coatings. It is found that the electronic descriptor ψ can well predict the atomic escape energy and thus the corrosion resistance of Ta-based binary alloys with the coefficient of determination R 2 of 0.804 and 0.949, respectively. Among them, TaW and TaCr alloys exhibit the most excellent corrosion resistance with the lowest I corr (<1.59 × 10 −7 A cm −2 ) and the highest U corr (> −0.011 V vs SHE) because of the largest −IpCOHP values and thus the strongest binding strength. The screening method is also applicable to the other alloys.

“…Copper is a metal widely used in different fields by virtue of its excellent electrical conductivity, heat, ductility, and other characteristics, such as electrical, light industry, machinery manufacturing, and defense industry. − It is very easy for electrons to be lost and be corroded in the process of use due to their activity, leading to the destruction of the metallographic structure of copper, thus affecting its use value and bringing economic losses and potential dangers . In industrial production, in order to save costs, we usually use some strong acidic solution to wash the copper to remove the corrosion-induced oxides on the copper.…”

The pumpkin leaf was extracted by the decoction method, and it was used as an eco-friendly, nontoxic inhibitor of copper in 0.5 M H 2 SO 4 corrosion media. To evaluate the composition and protective capacity of the pumpkin leaf extract, Fourier infrared spectroscopy, electrochemical testing, XPS, AFM, and SEM were employed. The results showed that the pumpkin leaf extract (PLE) is an effective cathode corrosion inhibitor, exhibiting exceptional protection for copper within a specific temperature range. The corrosion inhibition efficiency of the PLE against copper reached 89.98% when the concentration of the PLE reached 800 mg/L. Furthermore, when the temperature and soaking time increased, the corrosion protection efficiency of 800 mg/L PLE on copper consistently remained above 85%. Analysis of the morphology also indicated that the PLE possesses equally effective protection for copper at different temperatures. Furthermore, XPS analysis reveals that the PLE molecules are indeed adsorbed to form an adsorption film, which is consistent with Langmuir monolayer adsorption. Molecular dynamics simulations and quantum chemical calculations were conducted on the main components of the PLE.

“…Furthermore, pi electroncontaining compounds with functional groups such as -N=N, -C=N, and ˃NH often exhibit corrosion properties (8,9). N-and S-heterocyclic compounds are the best corrosion inhibitors for copper in alkaline environments (10)(11)(12). Organic chemicals have a long history and are by far the most advanced and economical tool employed by manufacturers.…”

Corrosion poses a significant challenge for numerous industries. The use of corrosion inhibitors is essential within these industries. The efficacy of environmentally friendly corrosion inhibitors should remain high even when used at low concentrations. In the present study, the compound 4- fluorophenyl-2,5- dithiohydrazodicarbonamide (FTSC) was used as a corrosion inhibitor for brass in 3.5% NaCl solution. The inhibitor efficiency was determined by using a series of electrochemical techniques such as open circuit potential (OCP), potential dynamic polarisation (PDP), linear polarisation resistance (LPR), and electrochemical impedance spectroscopy (EIS). All experimental tests have been done in stagnant conditions. The findings of the experiments revealed that the compound FTSC looked to be of the cathodic type. Furthermore, the maximum inhibitor efficiency was reached at 98.28% at 1 × 10-3 and at an immersion time of 1 h. The current density was reduced from 16.5 to 0.284 A.cm-2. The adsorption of compound on the brass surface in 3.5% NaCl solution obeyed the Langmuir isotherm with a low negative value of the standard Gibbs free energy of adsorption (-33.8 kJ/mol ΔGads (chemisorption and physisorption). The results confirmed that the compound FTSC can be used as a corrosion inhibitor for brass in 3.5% NaCl.
