“…Besides, it was shown that BTAH is the only inhibitor that provides effective protection of copper archeological artifacts during preservation process [49,52]. For example, it was shown that BTAH can completely inhibit the corrosion of cupronickels in salt water [4,18,19,53] as well as in acidic [37,54,55] environments. Based on enthalpy of adsorption calculations, these studies showed that the obtained values agreed very well with the value obtained for pure copper in the same media.…”

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 subject is attracting an increasing attention in efforts to elucidate the mechanism of inhibitive action [10,11,[32][33][34][35][36][37][38][39][40]. Most of these studies were primarily concerned with the equilibrium properties of the protective film and its effects on the anodic and cathodic partial reactions.…”

Most of the common inhibitors that are used commercially to control the corrosion of steel in neutral solutions are not environmentally friendly. Therefore, use of inhibitors with low toxicities is preferred in industries. The phosphates are inorganic inhibitors with relatively low toxicity that are used in different applications. The solution hydrodynamics is also one of major factors that influence the corrosion behavior of metals and the performance of inhibitors in corrosive systems. Present work is a systematic investigation of the combined effects of inhibitor concentration and hydrodynamic conditions on the electrochemical corro sion behavior of St37 steel in 3.5% NaCl solution containing potassium phosphate. The obtained results showed that behavior of phosphate under hydrodynamic conditions is influenced significantly by its concen tration. When the phosphate concentration was relatively high (5 mM), the inhibition efficiencies were not changed by variation of electrode rotation speed. It was attributed to the little influence of hydrodynamic conditions on stability of the protective layers formed on metal surface. It was also observed that at lower phosphate concentrations (less than 1 mM), the inhibitor performance decreased significantly applying hydrodynamic conditions due to the formation of frail and weak protective films on metal surface.

“…The electrochemical behavior of cupronickels has been extensively studied under different experimental conditions using various techniques [2][3][4][5][6][7][8][9][10][11]. It was reported that the increase of Ni-content improves the corrosion resistance of the alloy at high chloride concentrations (>0.5 M) [12].…”
