Abstract: Different types of fasteners are used in aerospace applications. E40CDV20 is a high strength hardened tempered steel. For high strength fasteners, different types of coatings are used for improving surface protection and achieving desired mechanical and surface properties. Evaluation of corrosion resistance of aluminium IVD which is used for high strength alloy steel fasteners has been carried out in this paper. Fasteners made out of high strength alloy steel materials namely E40CDV20 is used in this study. Scanning electron microscopy is done to evaluate the morphology of the coating. Salt spray test is conducted for the evaluation of corrosion resistance of aluminium IVD of coatings on E40CDV20 steel fasteners.
