Investigation and Feasibility Study of Nano composite Coatings

Composite coatings are obtained by simultaneously placing non-conducting and insoluble particles inside the metal substrate. These coatings have desirable mechanical properties and are more resistant to abrasion and corrosion than metal coatings. The degree of increase in their resistance depends on the morphology of the neutral fine particles inside the composite coating and their amount. Reducing the grain size of the substrate as well as reducing the diameter of the reinforcing particles improves the properties of the composite coating. Due to its simplicity and cheapness, low process temperature, ease of achieving nano structure and also producing high density and porosity-free coatings, electrical deposition method is one of the suitable methods for applying these coatings and has received special attention in the last few decades by researchers.
