“…This could be due to the Cu–BTA complex formation, as BTA was adsorbed on the copper surface. Generally, the Cu–BTA complex formation acts as a mixed-type inhibitor to retard the oxidation of copper and reduction in oxygen [ 7 , 9 ]. The breakdown potential ( E b ) seen in the BTA-added specimens indicated that the Cu−BTA complex has an effective passive property [ 9 ].…”

Notably, the Cu−BTA complex acts more effectively as an anodic corrosion inhibitor [ 32 ].…”

“…When copper is immersed in a solution containing BTA, it is believed that BTA forms a protective layer in the solutions [ 7 ]. The corrosion-inhibiting mechanism of BTA is generally accepted as the formation of a protective layer on the Cu surface by the formation of a Cu−BTA complex by a Cu−N bonds in BTA [ 8 , 9 ]. Although there is controversy regarding BTA inhibiting mechanisms, many researchers have studied BTA as an effective inhibitor for different conditions.…”

“…Ross and Berry investigated BTA inhibitory effectiveness under 10% H 2 SO 4 , low or high flow rate solution [ 13 ]. In addition, many studies on the inhibition efficiency of BTA under various conditions were conducted [ 7 , 9 , 14 , 15 , 16 ].…”

Carbonaceous residues on copper pipes during the manufacturing process are known to be one of the main causes of pitting corrosion on copper pipes. This study examined the corrosion-inhibiting effect of benzotriazole (BTA) on C12200 copper pipes with carbonaceous film in synthetic tap water. In the absence of BTA, localized corrosion mechanisms due to galvanic corrosion, crevice corrosion, and oxygen-concentration cell were proposed in the boundary part of the carbonaceous film on the copper through X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) with energy dispersive spectrometer (EDS) analyses. Electrochemical tests showed that BTA inhibits corrosion by forming Cu−BTA complexes on all over the copper surface where carbonaceous film is present. BTA mitigates galvanic corrosion and crevice corrosion at the boundary of the carbonaceous film and suppresses the formation of oxygen-concentration cells through the formation of a Cu−BTA complex.

Corrosion inhibition potential of three synthesized benzotriazole (BTA) derivatives namely, 1‐(prop‐2‐yn‐1‐yl)‐1H‐benzotriazole (Inh 1), 2‐[2‐(1H‐benzotriazol‐1‐yl)ethyl]‐1H‐isoindole‐1,3(2H)‐dione (Inh 2) and 1‐(4‐nitrobenzyl)‐1H‐1,2,3‐benzotriazole (Inh 3), on brass C68700 in NaCl 3 % was evaluated using potentiodynamic method. The results show that the examined molecules are good inhibitors for brass and behave as mixed type inhibitors. Inhibition efficiency (IE %) increases with the inhibitors concentration to reach 80.89 %, 83.70 % and 92.13 % at 15 ppm for Inh 1, Inh 2 and Inh 3 respectively. Additionally, the calculated DFT descriptors are in good agreement with the experimental inhibition efficiencies.
