摘要

The aqueous extract of Neolamarkia Cadamba (NC) bark was investigated as corrosion inhibitor foraluminium alloy (AA) in 1 M NaOH solution. The techniques employed for corrosion inhibition areweight loss, polarization resistance, Tafel polarization and electrochemical impedance spectroscopy(EIS). The inhibition efficiency increases with increasing the concentration and shows maximuminhibition efficiency (87 %) at optimum concentration (0.6 g/L). Polarization study revealed that it is amixed type inhibitor. The existence of protective film on the surface of AA was confirmed by thescanning electron microscope (SEM).
