Özet:

 

The inhibition of C38 steel corrosion in 1M HCl solution by 4-Amino-3-hydrazino-5-mercapto-1,2,4-triazole (AHMT) at 308K was investigated by means of weight loss, electrochemical polarization and electrochemical impedance spectroscopy (EIS). Results showed that AHMT performed as a good inhibitor for C38 steel corrosion in 1M HCl solution and it attains an efficiency of more than 87% at 10-2 M at 308K. The inhibition efficiency increases with an increase in the concentration of AHMT. Polarization curves show that AHMT is a cathodic inhibitor. The results obtained from the different methods are in good agreement. The adsorption of AHMT molecules on the C38 steel surface obeys Langmuir adsorption isotherm. The adsorption free energy of AHMT on C38 steel (-34.88 kJ / mol) involves two types of interaction, chemisorption and physisorption of the inhibition on the metal surface. .
