Benzotriazole (BTAH) is an excellent inhibitor for the corrosion of copper and many of its alloys in unpolluted media. Protection is attributed to the formation of a film of Cu(I)BTA. Injection of sulfide ions into a benzotriazole inhibited salt wate

The kinetics of interaction of benzotriazole (C6H5N3, BTAH) with the surface of copper in salt water were studied using an electrochemical quartz crystal microbalance and X-ray photoelectron spectroscopy (XPS). Upon injecting BTAH into the electrolyt

While benzotriazole (BTAH, C6H5N3) has long been known as an efficient inhibitor for the general corrosion of copper, this paper documents the occurrence of intergranular corrosion (IGC) of copper in a salt solution (3.5 wt.% NaCl) in the presence of

Benzotriazole (BTAH) is shown to inhibit the corrosion of the Cu10Ni alloy in salt water polluted by sulfide ions. The presence of sulfide ions (at 2 ppm) decreases the inhibiting efficiency of BTAH against the corrosion of Cu10Ni alloy. This is illu

Benzotriazole (BTAH) and copper ions exhibit synergistic effects on the electrochemical impedance spectroscopy and corrosion behavior of iron in sulfuric acid. The presence of submicro- and micromolar amounts of Cu2+ ions along with millimolar amount

Benzotriazole (BTAH) is shown to decrease the extent of localized corrosion of alpha brass in salt water contaminated by sulfide ions. The results are interpreted in terms of competitive adsorption of BTAH and sulfide ions on the brass surface and in

The results presented show that benzotriazole (BTA) inhibits the absorption of hydrogen into iron which is cathodically polarized in an acid (pH {approx_equal} 1.7) sulfate solution. Analysis of the results indicates that BTA inhibits also the hydrog

The addition of benzotriazole (BTA) to 0.1 M sodium nitrite solution produces an inhibitive effect on the stress corrosion cracking (SCC) of α-brass under applied anodic potential. The maximum stress and the time to failure increased with the BTA co

The blending of benzotriazole (BTAH) and thiourea (TU) was shown to exert synergistic or antagonistic effects on the anodic dissolution of copper at pH ≈ 1.8 depending on their concentrations in the blend. While synergism was observed in blends wit

The inhibiting effect of benzotriazole (BTA) on the corrosion of α-Al-bronze (Cu-7% Al) in 3.4% NaCl was studied. BTA showed good inhibition effects from short up to extended periods of time (about six weeks). The morphologies of the alloy surface w
