use of AZARDIRACHTA INDICA AND GUAR GUM as green corrosion inhibitors FOR ALUMINIUM MILD STEEL AND TIN IN ACIDIC MEDIUM

Abstract

Corrosion developments are accountable for various fatalities primarily in the industrialized possibility. The best way to ignore this problem is inhibition or protection. Among the several approaches to inhibit or stop damage or dissolution of metal exterior, the corrosion inhibitor is one of the superior method of corrosion defence and unique for most beneficial uses in the industry. Over the years, significant efforts have been made to introduce suitable corrosion inhibitors of a natural preliminary point in various corrosive media. The focus of our study is based on amplification of Green corrosion inhibitors which consider as eco-friendly and do not contain heavy metals or other poisonous compounds obtain from various parts of plants either it is leaves, roots and stem dry powder or water and alcoholic extract of plants. The study of natural product starting point as corrosion inhibitors is suitably the subject of general study due to minimum budget and environment friendliness of plant products and it is the major substitute for replacing synthetic inhibitors. In our study, Guar Gum and Azardirachta Indica has taken as Green corrosion inhibitor for Mild Steel, Aluminium and Tin corrosion in acidic medium. The selection of inhibitor made on extensively literature and their capability and tenability of oxidative conditions, whether selection of metals based on their domestic and industrialized uses. Weight loss methods, Kinetic parameters, Thermometric studies and Adsorption isotherms used to define their efficacy and applicability as Green inhibitor for condense corrosion of prescribed metals. Surface morphology changes confirmed by Scanning electron microscopy analysis. newlineIn our obtained results we found Neem (Azardirachta Indica) and Guar gum (Guaran) both as good inhibitors for defence corrosion but Neem is more potent and stably active due to the presences of more active components. newline newline newline newline
