ASSESSMENT OF THE CORROSION INHIBITION POTENTIALS OF Terminalia ivorensis LEAVES EXTRACT ON STEEL...

The goal of this study is to see how well Terminalis ivorensis leaves extract can prevent steel from corroding in an alkali media. The wear and tear potentials of corrosion on metals, as well as the financial implications for users, have made it a serious concern in the industrial world. As a result, the corrosion inhibition potentials of Terminalia ivorensis leaf extracts on steel in an alkali media employing sodium hydroxide solution had to be evaluated. The plant extract was used on mild and galvanised steel in a 3.0 M sodium hydroxide solution to achieve this (NaOH). The NaOH solution and 5, 10, and 15 g/l of plant extract were used in the weight reduction approach (3.0 M). Both Steels were plunged for 18 days and were examined every three days. In the alkali media, the plant extracts caused a loss in weight for galvanised steel but no obvious change for mild steel. On galvanised steel, the plant extract exhibits good corrosion inhibitory potentials, but not on mild steel. The research with the greatest concentration (15.0 g/l) also had the highest inhibitory efficiency of 77.05. The presence of several significant organic functional groups with some oxidative covering capability in the form of coating can be connected to the inhibitory potential of Terminalia ivorensis leaf extract.
