Inhibition behaviour of mild steel by three new benzaldehyde thiosemicarbazone derivatives in 0.5 M H₂SO₄: experimental and computational study

Three new benzaldehyde thiosemicarbazone derivatives namely benzaldehyde thiosemicarbazone (BST), 4-carboxyl benzaldehyde thiosemicarbazone (PBST) and 2-carboxyl benzaldehyde thiosemicarbazone (OCT) were synthesized and their inhibition effects on mild steel corrosion in 0.5 M H 2 SO 4 solution were studied systematically using gravimetric and electrochemical measurements. Weight loss results revealed that PBST exhibited the highest inhibition efficiency of 96.6% among the investigated compounds when the concentration was 300 µM. The analysis of polarization curves indicated that the three benzaldehyde thiosemicarbazone derivatives acted as mixed type inhibitors and PBST and OCT predominantly anodic. The adsorption process of all these benzaldehyde thiosemicarbazone derivatives on Q235 steel surface in 0.5 M H 2 SO 4 solution conformed to Langmuir adsorption isotherm. Scanning electron microscopy was conducted to show the presence of benzaldehyde thiosemicarbazone derivatives on Q235 mild steel surface. The results of theoretical calculations were in good agreement with that of experimental measurements.

In the present work, the Curam drug was used as an eco-friendly corrosion inhibitor for the protection of stainless steel 304 (SS-304) in 2.0 M HCl solution. The inhibition efficiency was determined by mass loss (ML), Potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) measurements. The surface morphology analysis carried out using Fourier transform infrared spectroscopy (FT-IR) and atomic force microscopy (AFM). ML data prove that with an increase in the temperature, Curam still exhibits good anti-corrosion performance. The inhibition efficiency of Curam can still be maintained at about 72% at 318 K. The data of electrochemical measurements indicate that Curam is the mixed-type inhibitor. The adsorption process of Curam on the SS-304 surface obeys the Langmuir adsorption isotherm. FT-IR and AFM analysis showed the excellent inhibition performance of Curam for SS-304 dissolution in an acidic medium. The data obtained by chemical and electrochemical measurements are in good agreement with one another.
