Nanomaterials (nanocrystalline materials) are materials possessing grain sizes on the order of a billionth of a meter. They manifest extremely fascinating and useful properties, which can be exploited for a variety of structural and non-structural applications. Nano technology is used as a tool to complement, develop, and advance different applications, surface treatments and coatings have greatly benefited from this technology. A coating is a relatively thin layer of material that applied to cover a substrate. Coatings are utilized for a variety of reasons. One of the most common industrial needs for coatings is to improve the surface properties of a substrate. The improved properties include wear resistance, corrosion resistance, and mechanical properties
