Description
Inhibiting Chloride-Induced Corrosion of AISI 304L using novel corrosion inhibitor was investigated in 1.0 M HCl solutions. Methods employed were weight loss, electrochemical and scanning electron microscopy. The research was achieved by injecting varied concentrations of the novel corrosion inhibitor into the corrosive solutions containing the adsorbent. Analysis of results showed that the injected novel inhibitor possessed commendable inhibitive features in HCl solutions. Results from both weight loss and potentiodynamic polarization measurements were in tandem. The inhibitor concentration varied linearly with the inhibition efficiency, surface coverage and resistance polarization up to some a point, but had an inverse relationship with the corrosion rate and current density. The displacement in Ecorr was calculated to be 72 mV which suggests that the extract acted as a mixed type inhibitor. Kinetic study …
