“…However, the copper-benzotriazole complex was found to be evaporated from the dipped bronze surface at about 230°C with an exothermic reaction. On the other hand, the inhibiting effect of BTAH on the corrosion of a-Al-bronze (Cu-7% Al) in 3.4% NaCl was studied by Ashour and co-workers [15]. They showed that BTAH had a stronger inhibiting effect on the anodic dissolution of copper than on the cathodic reduction of oxygen.…”

“…In this way, a coordination compound can be formed on the copper surface which can act as an inhibitor against corrosion. This makes benzotriazole one of the most efficient inhibitors for the corrosion of copper and its alloys in aqueous media [13][14][15][16][17][18][19][20]. Generally, BTAH acts as an anodic corrosion inhibitor [21][22][23][24][25][26][27] via its physisorption [22,23] on the copper surface that follows, in most cases, Langmuir isotherm [21,22,25,[28][29][30].…”

A continuing challenge in materials design is the achievement of high operational efficiency through improvements in performance criterion, particularly its service life-time characteristics. Benzotriazole (BTAH) has now been in use for many years for the protection of copper and copper alloys against various forms of corrosion. In this review, the chemistry of BTAH and theories regarding its mode of action are summarized. Also, a survey of the reported work in both clean and polluted environments is documented. More interestingly, the adverse effect of BTAH on the corrosion of Cu and Cu alloys in sulfide polluted environments is introduced.

The effect of benzotriazole (BTAH) on the corrosion fatigue behavior of α‐Al bronze in 1 M LiBr solution has been investigated using reverse bending technique during testing it in LiBr/H2O system. The adsorption equilibrium estimated to be 1431.25 M−1 while the free energy of adsorption to be −27.968 kJ mol−1. The BTAH feature found to improve the fatigue life to a value near to that of α‐Al bronze in air. The optical and scanning electron microscopy for the α‐Al bronze for the fatigued in air, revealed that the fracture mode was transgranular and that the initiation and propagation was transcrystalline. α‐Al bronze fatigued in 1 M LiBr showed less fatigue resistance when compared to that of α‐Al bronze fatigued in air. The addition of 0.02 M of BTAH to 1 M LiBr increased the fatigue life and fatigue strength for α‐Al bronze where its fatigue behavior curve was close to that of air. The results demonstrated obviously a reduction of the corrosion fatigue resistance of α‐Al bronze in 1 M LiBr solution but it has a considerable increase in the presence of BTAH.

“…However, benzotriazole (BTA) is the mostly used inhibitor from practical point of view because it shows very high inhibition efficiency in nearly neutral chloride containing aqueous solution. Numerous studies have been performed on inhibition effect of BTA for the corrosion of copper‐base alloys in aqueous chloride solution 19–24.…”

The effect of benzotriazole (BTA) on the corrosion of a new type copper‐manganese‐aluminium (CMA) alloy in artificial seawater was investigated using dynamic electrochemical impedance spectroscopy (DEIS), linear polarization resistance, and Tafel extrapolation methods. Measurement results obtained from those three methods showed that corrosion rates decreased while BTA concentration increased. This clearly indicates that BTA inhibits the corrosion rate of CMA in artificial seawater. Although there are consistent results obtained from all these three methods, the results of the percent inhibition efficiency, IE (%), values obtained from DEIS method should be calculated from the charge transfer resistance (Rct) values obtained after 5 h.
