Inhibition of corrosion of mild steel in hydrochloric acid by natural plant leaves extract of of Bahunia Varigata
(Aapta), Azadirachta Indica (Neem), Pongamia Pinnata (Karanj), Santalum Album (Sandal Wood) and Astonia Scholaris
(Saptparni) has studied using weight loss measurement. It was, found that the leaves extract act as a good corrosion inhibitor for
mild steel in all concentrations of the extract. The inhibition action depends on the concentration of the leaves extract in the acid
solution.
