Natural products as corrosion inhibitor for aluminium alloy in tropical seawater

Abstract

The potential of natural products i.e. natural honey (NH), vanillin (VL) and tapioca starch (TS) as corrosion inhibitor for Al-Mg-Si alloy were studied in tropical seawater at room temperature. Weight loss and electrochemical measurements of Al-Mg-Si alloy as well as adsorption and their surface morphology in the presence of these natural products were investigated.
