Development of electrodeposited multilayer coatings: A review of fabrication, microstructure, properties and applications

The demand for robust engineering materials demonstrating good tribological performance under arduous service conditions has forged the development of novel coating and techniques. In field surface engineering, multilayer structures have attracted great interest. Electrodeposition offers a versatile controlled route to coatings in tribology. Electrodeposited can provide tailored electronic, magnetic, mechanical, wear-resistant corrosion-resistant characteristics as well an improved load-bearing capability. multilayered electrodeposits significantly exceed that single layers. This paper critically reviews fabrication, microstructure, properties potential applications electrodeposited coatings. Such powerful, complementary additions toolkit electrodeposition, enabling future advances. Critical aspects requiring further R & D endeavors are identified.
