“…Among methods which have been applied to minimize the dezincification phenomenon, the use of inhibitors is most efficient one. In this way, many types of organic and inorganic chemical compounds have been introduced as the corrosion inhibitor for copper and its alloys [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The inhibition mechanism is generally explained that inhibitor molecules which are able to donate electrons, form coordinative bonds in the presence of vacant d-orbitals in copper [5].…”

“…An anodic current peak ''A'' appearing at a potential of about À25 mV (SCE) is related to the formation of CuCl precipitation [20][21][22][23][24]. While, the anodic current peak ''B'' at about 100 mV (SCE) is related to the formation of cupric ions.…”

Complex self-assembled monolayers (SAMs) were prepared by modifying the adsorption of cysteine with dodecylacid (DAC) and with dodecylamine (DAM) on copper surfaces. Their protective effects against copper corrosion were investigated by potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) in 0.5 M HCl aqueous solution. Results show that SAMs suppress cathodic current densities and shift the corrosion potential toward more negative values. Two types of complex SAMs enhance the anticorrosion effect of cysteine SAMs. PM3 semi-empirical quantum calculations were used to obtain the quantum chemical parameters. The complex SAMs formed from cysteine and DAM have the higher E HOMO level and the better protection effect.

ABSTRACT. The corrosion inhibition of copper-nickel alloy by Ethylenediamine (EDA) and Diethylenetriamine (DETA) in 1.5M HCl has been investigated by weight loss technique at different temperatures. Maximum value of inhibitor efficiency was 75% at 35 o C and 0.2 M inhibitor concentration EDA, while the lower value was 4% at 35 o C and 0.01 M inhibitor concentration DETA. Two mathematical models were used to represent the corrosion rate data, second order polynomial model and exponential model respectively. Nonlinear regression analysis showed that the first model was better than the second model with high correlation coefficient. The reactivity of studied inhibitors was analyzed through theoretical calculations based on density functional theory (DFT). The results showed that the reactive sites were located on the nitrogen (N1, N2 and N4) atoms.
