Aluminum is using in many applications such as Automotive, Aerospace, Marine etc., due its thermal, chemical mechanical properties. Aluminum is lightweight and has high resistance to corrosive environment. This excellent resistance reduces maintenance costs, and reserves appearances. hardness of Aluminum is low which can be enhanced by coatings. The various parameter are studies like microhardness, resistance of corrosion and resistance against wear. electrodeposited coatings are in industry gaining more importance due to their simplicity of operation, low cost and ease to fabricate. Al2O3 is one of the hard coating materials and is used to coating different metals matrix. Mostly, composites containing of Al2O3 coating are favored for microhardness, wear resistance, high oxidation resistance and enhanced corrosion resistance. The nanocomposite of matrixes and coating layers are characterized by SEM. The morphology of the coated layers illustrations the deposition of fine-grained structures.
