“…Recently, a large number of thiazoles derivatives were reported as effective corrosion inhibitors for various metals and alloys including mild steel, copper and aluminum in acid, basic and neutral corrosive media using theoretical and experimental methods [10][11][12][13][14][15][16]. The selection of these compounds based on the facts that: the DHATs (a) can be synthesized from commercially available starting materials, (b) contain various adsorption centers including -NH 2 , -OH groups and heteroatoms along with extensive conjugation in form of hetero aromatic rings (c) they were effective even at very low concentration and (d) they were highly soluble in test medium.…”

“…Most of the well-known acid inhibitors are organic compounds containing nitrogen, sulphur and oxygen in their functional groups with aromatic and heterocyclic rings [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. These organic compounds can be absorbed on the metal surface, block the active sites on the surface and thereby reduce the corrosion rate.…”

The corrosion inhibition effect of the methanolic extract of Eucalyptus globulus leaves as an eco-friendly green inhibitor for corrosion control of carbon steel in 1 M H 2 SO 4 solution was studied using weight loss measurements and different electrochemical methods. It was found that E. globulus extract acts as a strong inhibitor. Results showed that this compound acts as a mixed-type inhibitor. As the inhibitor concentration increased, the charge transfer resistance of carbon steel increased and double layer capacitance decreased. The results of weight loss measurements were in good agreement with other electrochemical methods results. It was found that this green inhibitor acts through adsorption on the metal surface. In addition, adsorption obeys the Langmuir isotherm.

“…The increase in R ct value can be attributed to the formation of protective film on the metal/solution interface. On the other hand, the values of Capacitances double layer (C dl ) are decreased with increase in inhibitor concentration which is most probably is due to the decrease in local dielectric constant and/or increase in thickness of the electrical double layer, indicating that the inhibitors function by adsorption at the metal surface [25] [26]. Also the effect of temperature on the electrochemical impedance spectroscopy was studies at 30˚C, 40˚C, 50˚C and 60˚C.…”

Corrosion inhibition of mild steel in 0.5 mol/L H2SO4 was investigated in the absence and presence of different concentrations of thiosemicarbazide. The inhibition efficiency of thiosemicarbazide was studied by electrochemical impedance methods, potentiodynamic polarization and scanning electron microscopy at different inhibitor concentrations. Inhibition efficiency, corrosion rate and surface coverage were evaluated at different concentrations of thiosemicarbazide. Electrochemical impedance plots indicated that the presence of the inhibitors increased the charge transfer resistance of the corrosion process, increasing the inhibition efficiency. Polarization curves showed that this compound acted as mixed type inhibitor. The results of the investigation showed that this compound had good inhibiting properties for mild steel corrosion in 0.5 M sulfuric acid. The adsorption isotherm studies showed that Thiosemicarbazide adsorbed chemisorbed and formed a stable surface complex on the mild steel surface. And Langmuir obeyed the adsorption isotherm. Scanning electron microscopy analysis shows that, the surface morphology of the polished mild steel in the presence of thiosemicarbazide as inhibitor is smoother surface as compared with polished mild steel specimen in the absence of inhibitor.
