| Özet |
| Most industries struggle with corrosion. Corrosion inhibitors are needed in these sectors. Eco-friendly corrosion inhibitors should be effective even at low concentrations. In this work, the compound 2- Fluorophenyl-2, 5- dithiohydrazodicarbonamide (2F-TSC) was utilized as a corrosion inhibitor for copper in a 3.5% NaCl solution. The inhibitor efficiency was calculated by using a series of electrochemical methods like, open circuit potential (OCP), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS). All tests have been done in a stagnant condition. The results show that the compound 2F-TSC looked to be of mixed type. Furthermore, the maximum inhibitor efficiency was reached at 99.2% at 10-2 M 2F-TSC and 5 h. The adsorption of 2F-TSC on the copper surface in 3.5% NaCl obeyed the Langmuir isotherm with a negative value of the standard Gibbs free energy of adsorption of -35.4 kJ/mol (chemisorption and physisorption). SEM, EDX, and AFM confirmed the presence of 2F-TSC on the surface of copper. The adsorption of the inhibitor molecules on the Cu (111) surface was further verified by a Monte Carlo simulation study. The results approved that the 2F-TSC can be utilized as a corrosion inhibitor for copper in an aggressive solution (3.5% NaCl). |
