Özet

The influence of thioacetamide (TAcA), thiourea (TU) and thiobenzamide (TBA) on the corrosion of mild steel in 0.1 M H2SO4 solution has been studied in relation to the concentrations. The -CS-NH2 group is the common main group for these compounds and they differ only having different groups on the other side of the thiocarbonyl group. Electrochemical impedance spectroscopy (EIS) and polarization resistance measurement (RP) techniques have been used to obtain experimental data. The results showed that these compounds revealed a good corrosion inhibition, thiobenzamide being the most efficient and thioacetamide the least.
