Surface protection of copper by azoles in borate buffers-voltammetric and impedance analysis

Investigating metal‐inhibitor interaction with EQCM and SVET: 3‐amino‐1,2,4‐triazole on Au, Cu and Au–Cu galvanic coupling

“…Azoles have been studied employing several techniques, which confirm that these compounds have a high affinity for noble metals, because of the highly electronegative heteroatoms (sulphur, nitrogen, oxygen, etc.) present in their structure …”

“…Organic inhibitors are compounds that applied in very small concentrations are capable of effectively reduce the corrosion rate. Among these compounds those belonging to the group of azoles, which contain nitrogen and/or sulphur, are considered to be effective corrosion inhibitors for copper in a wide range of aggressive environments …”

Corrosion behavior of AISI 4130 steel alloy in ethylene glycol–water mixture in presence of molybdate

“…The free energy of adsorption DG 0 ads of the inhibitors on steel surface can be determined using the following equation [40]: DG 0 ads ¼ ÀRT lnðK ads  55:5Þ (12) where DG 0 ads is the standard free energy of adsorption and the value of 55.5 is the concentration of water in solution expressed in mol l À1 . The negative values of the DG 0 ads indicate that the spontaneous adsorption of MoO 2À 4 from ethylene glycol solution to the metal surface.…”

“…In practice, inhibitors are used for corrosion control in closed systems and as an alternative of efficiency-cost for materials use. The affectivity of some corrosion inhibitors depends upon the type of material, its properties and the corrosive environment [9,12]. The prevailing environmental conditions would usually determine the mechanism of the inhibitor action [13].…”

Compounds from the imidazole group as copper corrosion inhibitor in acidic sodium sulphate solution

“…Dobra inhibitorska svojstva u kiseloj sredini pokazala su mnoga jedinjenja od amino kiselina do azola [14][15][16][17][18][19].…”
