Now a days, Aluminium is used in multiple applications such as Aerospace, Automotive, Marine and Rail etc., due its unique mechanical, thermal, chemical properties. Aluminium is light in weight, offers excellent resistance to corrosion. This high resistance extends the life of equipment, significantly reduces maintenance costs and preserves outward appearances. But the hardness of Aluminium is very less which can be improved using ceramic coatings. In this paper we discuss the change in hardness and how the corrosion weight loss is affected with the use of Al2O3 and Al2O3+40TiO2 coatings.

Keywords: Aluminum, Ceramic coatings, Al2O3, Al2O3+40TiO2, Hardness, Corrosion test
