Overview

This study reports the corrosion inhibition of AISI 1020 carbon steel by expired prednisolone, suggesting potential applications in protective coatings.

Key Points

  • The maximum corrosion inhibition efficiency achieved was 90% at 298 K.
  • Polarization studies confirmed that prednisolone acts as a mixed-type inhibitor.
  • Electrochemical impedance spectroscopy indicated increased charge transfer resistance with higher inhibitor concentrations.
  • Surface characterization revealed significant reductions in corrosion on the metal surface.
