Abstract

Keywords Aluminum  HCl solution  Corrosion inhibition  Tender arecanut seed  AC impedance  Potentiodynamic polarization Introduction Aluminum and its alloys have emerged as strategically important materials in chemical processing industries owing to their exceptional physicochemical and metallurgical characteristics [1–4]. Due to their wide applications, they frequently come into contact with aggressive acid solutions during pickling, descaling, and electrochemical etching processes. These solutions dissolve the invisible adherent oxide film formed over the aluminum surface, which leads to enhancement of the corrosion rate and dissolution of the metal under such severe conditions [5, 6]. Moreover, in aggressive media, regeneration of the thin film may be delayed and pits generated, which may propagate further, leading to significant damage to the metal surface. Corrosion of aluminum surface in aggressive environments often leads to enormous economic losses. Corrosion inhibition of aluminum and its alloys is a subject of tremendous technological importance due to their wide range of household and industrial applications. For these reasons, inhibition of aluminum corrosion has attracted attention from many investigators [7–17]. Corrosion reactions can be significantly suppressed by incorporation of certain species into the surrounding environment [18–22].
