The unique features of aluminium alloy (AA6061) and its composite (AA6061-SiC composite) and their distinct advantages over aluminium metal have made them popular in many engineering applications such as automotive, aerospace, and structural components. However, aggressive media like acid, alkaline or chloride media reduces their corrosion and fatigue resistance, hence the workability of these materials. There is no evidence available in the literature about the systematic review of corrosion and inhibition of these materials in aggressive acid, alkaline and chloride media. Hence, the present review paper gains significant importance. One of the most feasible strategies for managing material corrosion is the addition of an inhibitor to an aggressive medium. A critical review of the inhibition performance of reported organic and inorganic compounds as inhibitors against the corrosion of AA6061 and AA6061-SiC composite in acid, alkaline and chloride media is summarised in this paper. A correlation between the chemical structure and inhibition of the activity of the inhibitors is discussed. The details of the types of inhibition process and the general mechanism of inhibition involved have been discussed.
