“…In the absence and presence of corrosion inhibitors, the O 1s spectra of a brass surface (Figure g,h) show two peaks at 531.6 and 533.64 eV, indicating the presence of Cu(OH) 2 and Cu 2 O . In the presence of inhibitors (Figure h), the peaks are less abundant.…”

A peak at 400.11 eV (Figure 12j) indicates the presence of C−NH 2 on the surface of brass in the presence of PTAH, which may be explained by the adsorption of PTAH on the brass surface.…”

“…BTA can provide a barrier of protection on the surface of the Cu-27Ni alloy, according to electrochemical impedance tests, which also caused the corrosion potential to shift to nobler states. BTA increased the Cu-30Zn alloy’s corrosion resistance as well . Using copper samples in a seawater environment, Younes et al evaluated the efficiency of certain tetrazoles and thiosemicarbazide derivatives at inhibiting corrosion.…”

The performance of 5-phenyl-1H-tetrazole (PTAH) and 5-(4-pyridyl)-1H-tetrazole (PyTAH) as corrosion inhibitors on copper and commercial brass in simulated seawater containing 3.5% NaCl was explored using electrochemical techniques. The surface of the tested samples was examined in the presence and absence of corrosion inhibitors utilizing scanning electron microscopy, energy-dispersive spectroscopy, and X-ray photoelectron spectroscopy. The PTAH inhibitor implied better performance for both samples. The results showed that PTAH excels PyTAH, with an inhibition efficiency of 97% for copper and about 96% for brass and an optimum concentration of 0.01 M. Surface investigations reveal that the presence of PTAH has significantly protected the copper and brass surfaces. The Langmuir adsorption isotherm presented that the inhibitors physiochemically adsorb on the sample surfaces, whereas the Arrhenius plot exposed a significant increase in the corrosion reaction activation energy after addition of the inhibitor, which clearly indicates its inhibition effect on copper and brass surfaces.

“…In contrast to the other investigated brasses, E cor values recorded during SSRT ( Figure 18 b) tended to ennoble at increasing strain. According to some authors [ 46 ], this could be due to a noble copper layer redeposited after dezincification. However, it is also possible that on this alloy, where surface silicon tends to form electrically insulating silicates [ 47 ], the formation of multiple cracks on the surface film predominantly speeds up the cathodic activity and consequently ennobles E cor .…”

Duplex α + β’ brasses are widely used in drinking water distribution systems for tube fittings, valves, and ancillaries because they are low cost, easy to fabricate, and exhibit high mechanical strength. However, depending on application conditions and alloy composition, they may undergo dealloying and stress corrosion cracking. In this research, three different brass types, two leaded (CW617N and CW602N) alloys and one lead-free brass (CW724R), were investigated to assess their corrosion behavior and susceptibility to stress corrosion cracking (SCC) in simulated drinking water (SDW) solutions containing different chloride concentrations, compatible with drinking water composition requirements according to Moroccan standard NM 03.7.001. The corrosion behavior was assessed by electrochemical tests such as polarization curve recording and electrochemical impedance spectroscopy (EIS) monitoring, coupled to SEM-EDS surface observations. The susceptibility to SCC was investigated by slow strain rate tests (SSRT). The tests showed that corrosion was mainly under diffusion control and chlorides slightly accelerated corrosion rates. All alloys, and particularly CW617N, were affected by SCC under the testing conditions adopted and in general the SCC susceptibility increased at increasing chloride concentration.
