The use of coatings on materials is now widespread in global manufacturing for reducing production cost and improving productivity, all of which are essential if industry is to remain economically competitive. As per industrial requirements materials may be get failed due to their mechanical properties like strength, hardness of these materials can be improved by coating. The durability of material depends on its quality. Good quality material is inherently durable. The durability can be increased by proper choice of materials propositioning, placing and curing. Another way of enhancing the durability of concrete is by applying a coating. The materials which are coated have high strength than that of the uncoated materials. Ceramic coatings can transform an ordinary metal into a high-performance surface. When applied by detonation gun, the coatings are dense, wear, corrosion & heat resistant, inert to acids, alkali and solvents. They improve the properties of any surface they’re applied onto. Because of higher energy application method coatings have higher particle-to-particle cohesive bonding which translates into higher quality coatings. In this paper, we review the difference in hardness and microstructures between the two different surface ceramic coatings applied on the aluminum by detonation gun.
