Based on the principles that govern material behavior, it has been established that a material or device with particles size less than 100 nm length is in the nanotechnology domain. These particles primarily promote the mechanical and metallurgical properties of composite coatings in the areas of micro-hardness, corrosion resistance and tribological control and frictional and wear properties. Therefore, nanotechnology helps in characterizing the co-deposit of compo‐

Electro-deposition is a deposition technique that applies metallic coatings to metallic or other conductive surfaces through electrochemical processes. It is an excellent means of producing a composite coating successfully on metal surfaces. In this method, the distribution of particles is uniform, the rate of deposition is high, and the temperature of operation is low (i.e., <

C). Compared to high-temperature methods such as pyrometallurgy and powder metal‐
