Corrosion is the deterioration of metals by chemical interaction with their environment. Aluminium finds extensive industrial and household applications where it gets exposed to variety of aggressive and corrosive environments. The chemical attack at the Al surface breakdowns the protective oxide layer and subsequently leads to a sequence of electrochemical reactions causing its corrosion. The present study investigated the corrosion behavior of Al in saline environment (0.5 M NaCl) using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. The Nyquist and Bode plots show the decreased polarization resistance and impedance with immersion time. Tafel plots indicate the high corrosion rate (mm/yr) 1.13 at scan rate 0.001 V/s. Scanning electron microscopy (SEM) reveals the characteristic pitting corrosion in Al under saline environment.
