“…There is an apparent connection between the corrosion of the alloy and the active components in the solution, understanding the corrosion behavior requires more than just focus on the properties of the solution [45,46]. In view of the complex corrosion behavior of brass in the AH system, the behavior of various active components in the solution should be considered in the exploration of corrosion mechanisms.…”

The disposal of scrap rubber, represented by retired tires, has achieved industrial achievements, but the handling of brass-coated steel wire as a structural reinforcement in retired tires has received little attention. A feasible and efficient method of acquiring economical resources is proposed to extract copper and zinc (Cu-Zn) from brass-coated steel wire. With 20% ammonia, 10% hydrogen peroxide, and a liquid-solid ratio of 10, the brass coating almost completely dissolved in 5 minutes. This technique may remedy the challenge of weak dissolving efficiency brought on by the dual phase microstructure of brass. Electrochemical measurements and density functional theory (DFT) simulations assist in verifying that hydrogen peroxide decreases the resistance of the corrosion and that OH- and O-2 in solution are the main contributors to the dissolution. In addition, the AH effectively enhances the corrosion of the α phase in brass, which is notably evident in comparable works. This effective strategy broadens the application of retired tires and provides a new method for extracting Cu-Zn resources.

“…With the improvement of hardware and software, recently, quantum chemical methods like functional density theory (DFT)" has been used as fast and powerful tool to predict and understand corrosion inhibition performances of inhibitors [38]. Although there is an extensive literature on the corrosion properties of benzotriazole on steel and copper [39,40], a protective coating is created by utilizing a tiny inhibitor dose to delay the corrosion reaction [41][42][43].…”

3-(4-chlorophenyl)-7-methyl-5H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazin-6(7H)-one (CTT) was synthesized and evaluated as corrosion inhibitor for copper in one molar HNO3. The adsorption properties for the synthesized CTT were determined by experimental and theoretical methods in acid environment. The chemical method such as mass loss method (ML), DC potentiodynamic polarization (PDP) and AC impedance (EIS) techniques were utilized to determine the inhibitive behavior of CTT. Outcome data obtained from these methods displayed that with increasing the concentration of CTT its inhibition efficiencies (%IE) increases and reached 91.5% at 24x10-6 M , 25oC using EIS technique. The presence of CTT reduces the capacity of the double layer (Cdl) and improves the charge transfer resistance (Rct) in a solution of one molar nitric acid. CTT is a mixed-type inhibitor from the data obtained from the polarization curves. The attained data indicated that CTT was physically adsorbed onto the Cu surface in accordance for the Langmuir adsorption. The surface protection examination was carried out using scanning electron microscopy (SEM), Energy Dispersive X-ray (EDX) and atomic force microscope (AFM). Also, The quantum chemical parameters of CTT were computed and discussed. The results of several methods are in agreement with each other.
