“…The initial decrease in mass and increase in frequency refer to the corrosion of copper (before injection of BTAH). The corrosion of copper in this medium is a complex process that leads to the formation of soluble and insoluble corrosion products such as CuCl À 2 , CuCl 2 , CuCl, Cu 2 O, Cu 2 (OH) 3 Cl,...etc. [48,49].…”

“…1, 2). There is strong evidence that the corrosion rate of copper in the presence of BTAH is negligibly small compared to that in its absence [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Had BTAH merely stopped the corrosion reaction, one would have observed a constant mass and constant frequency after addition of BTAH.…”

“…Benzotriazole (C 6 H 5 N 3 , BTAH) has been extensively studied as an inhibitor for the corrosion of copper and many of its alloys [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], for dezincification of brass [17,18] and as additive in the etching [19], electrodeposition [20][21][22] and in the chemical mechanical polishing of copper [23][24][25]. It has also been reported to inhibit the corrosion of iron [26][27][28], cobalt [29], zinc [30], and nickel [28] and to enhance the resistance of tin bronze to oxidation in air [31].…”

A quartz crystal microbalance study of the kinetics of interaction of benzotriazole with copper

The kinetics of interaction of benzotriazole (C 6 H 5 N 3 , 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 electrolyte, three regions appear in the time response of the microbalance. Region I (at short time of few minutes), exhibits rapid linear growth of mass with time, which is attributed to the formation of a protective Cu(I)BTA complex. Region II reveals attachment of BTAH at a slower rate onto the inner Cu(I)BTA complex. Region III is a plateau indicating that the BTAH film attains an equilibrium mass and thickness, which increase with the concentration of BTAH. The intensity of the N1s peak in the XPS spectra increases with the time of immersion, indicating more BTAH on the surface. The results suggest a duplex inhibitor film composed of an inner thin layer of Cu(I)BTA and an outer layer of physically adsorbed BTAH which increases in thickness with time and BTAH concentration. They also offer an explanation for the much documented findings of simultaneous increase of the polarization resistance and decrease of double layer capacity with inhibitor concentration and time of immersion.

“…Benzotriazole (BTAH) was shown to be the most effective inhibitor for copper and its alloys in various aggressive environments. Ever since the early works of Cotton and co-workers [6,7] there has been a continuing interest in the mechanism of inhibition and in various aspects of the interaction of BTAH with the oxide-free and oxide-covered copper surfaces [4,[8][9][10][11]. The aim of the present review is to briefly summarize and document the reported literature dealing with the use of benzotriazole to inhibit the corrosion of copper and its alloys in different environments.…”

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.

“…Since then, it has become the most common of copper artefacts. many laboratory studies were compared BTA with some traditionally protective coatings and a new corrosion inhibitors in all these studies benzotriazole showed good efficiency as a good corrosion inhibitor and often presented the best results [16][17][18][19][20]. The efficiency of Met as good corrosion inhibitor of copper attributes to the strong banding between copper surface and the formed film.…”

:The research aimed to evaluate the efficiency of three compounds from preferred corrosion inhibitors of copper artifacts to be used to protect silver artifacts. The compounds are Benzotriazole (BTA), L-methionine (Met.) and Sodium decanoate (NaC 10 ), each inhibitor was tested with and without Nano-alumina. The evaluation of these compounds was performed using the electrochemical measurements (Potentiodynamic (pt) and Electrochemical Impedance Spectroscopy (EIS)) and accelerated corrosion test with H 2 S gas and water resistance test within enclosed chamber. The treated silver coupons with studied inhibitors were examined using microscopes SEM, PM and AFM to appear some important features of the formed film. The study was carried out on manufactured coupons of the silver alloy with copper. The results revealed that BTA and NaC 10 in presence and absence Nanoalumina have good efficiency in the protection of the silver coupons in the corrosion conditions used in the tests.
