An eco-friendly method for preventing corrosion in low-carbon steel using an extract from Guazma tomentosa leaves.

Abstract

Corrosion engineers now consider low-carbon steel an absolute must for industrial applications. According to organic compounds, N, S, O, and heterocyclic chemicals with polar functional groups and conjugated double bonds in the extract showed promise as inhibitors. Powder X-ray diffraction and energy-dispersive X-ray spectroscopy investigations supplemented the scanning electron microscopy (SEM) to characterize the surface morphologies. An acidic solution was used to conduct corrosion inhibition tests on low-carbon steel with Guazma tomentosa (GUTLE) leaf extract. Electrochemical techniques, weight loss, FT-IR, XRD, EDAX, and SEM were employed in these investigations. Thermodynamic investigations are computed and reviewed as well. Thenbachai tree, or Guazma tomentosa, is a member of the Sterculiaceae family.
