Purpose: Corrosion is the process of degradation of the materials due to its interaction with the atmosphere. All materials are susceptible to corrosion. Among all other materials metals are the most widely used materials. Metals are widely used for their properties such as high strength, ductility, thermal resistance and formability. So it is important to establish suitable methods to inhibit the corrosion of such materials. In this paper the material mild steel has been selected as it is one of the most commonly used material. The method used for corrosion inhibition is anodization followed by sealing using an ecofriendly corrosion inhibitor. The eco-friendly material that is tested in this paper is Emblica officinalis more commonly called as Amla. The material is first anodized in a 50% NaOH solution at elevated temperatures and their corresponding corrosion inhibition is studied using weight loss method. Properties such as adhesion, heat resistance are also tested for the material. FTIR is used to identify the coating produced by anodizing and also for the identification of the functional bonds in the ecofriendly corrosion inhibitor.
