Corrosion Inhibition of Aluminium Alloy by Chemical Inhibitors: An Overview

Abstract

Abstract Aluminium is a widely used metal in every sphere of human endeavour. Hence, its corrosion comes as no amazement. Globally, studies are being conducted to suppress this unwanted action of corrosion. Chemical inhibitors are the focus but besides chemical inhibitors, plant extracts could as well be used to inhibit the mechanism of corrosion. Polymeric inhibitors fall under this category. It is believed that these chemical inhibitors should be employed in industrial purposes. They will save millions and produce little to no toxic emission. From findings, the various techniques employed in investigation of corrosion inhibition are weight loss (the fundamental and most common method), electrochemical impedance spectroscopic (EIS) measurements and potentiodynamic polarization.
