Investiga.ion into the Inhibition of pitting corrosion in mild steel a.ound hea.y sa.t deposits by some selected seconda.y pla.t meta.olites—a.ka.oid extra.t (a.SML), sa.onin extra.t (SESML a.d fla.onoid extra.t (FESML) of na.ura. product origin—Strongylodon ma.robotrys wa. successfully completed with the a.d of electrochemica. impeda.ce spectroscopy, potentiodyna.ic pola.iza.ion, gra.imetric a.d ga.ometric experimenta.ion. The resea.ch proved tha. the selected seconda.y pla.t meta.olites were excellent inhibitors of mild steel in the sa.t wa.er environment a. inhibition efficiency wa. recorded a. 99.2%, 92.6% a.d 84.7% for a.SML, SESML a.d FESML. The inhibitors showed higher inhibition a. lower tempera.ure due to frequent sca.e redeposition from a.ita.ion in tempera.ure rise a.d loss in collision of the molecules. The potentiodyna.ic pola.iza.ion result confirmed the reduction in the loss of electrons a. the a.ode by the inhibitors tha. would ha.e trigger oxida.ion rea.tion tha. ca.ses the a.ode to corrode. Cha.ge tra.sfer resista.ce reflected the ma.imum inhibition efficiency obta.ned for mild steel a. ma.imum concentra.ion a.d the decrea.e in double la.er ca.a.ita.ce is due to the decrea.e of the a.ea.where electrolyte is present due to the forma.ion of inhibitor film. Thermodyna.ic investiga.ion shows tha. the inhibitor ha. the potentia. of increa.ing the energy of the intermedia.e, reducing both the number of collisions, a.d number of pa.ticles tha. ha.e enough energy to rea.t a.d a.so number of corrosion rea.tion pa.ticles with the correct orienta.ion.
