Using the weight loss method and scanning electron microscopic examinations, the extract of Andrographis paniculata leaves in various concentrations was examined as a corrosion inhibitor of mild steel in 10% HCl. The weight loss findings demonstrated the effectiveness of plant extract as a corrosion inhibitor at various doses. Studies using scanning electron microscopy confirmed the enhanced surface condition caused by adsorption for corrosion protection.
