Review of Studies on Corrosion of Electrodeposited Nanocrystalline Metals and Alloys

Abstract

Nanocrystalline materials are now gaining vast interest due to their outstanding physical, mechanical and chemical properties. Electrodeposition is an economical, reliable and viable technique in producing nanostructured materials as compared to other available methods. Recently, due to the high potential of nanocrystalline materials in anti-wear and corrosion resistance coating applications, the interest to develop better nanostructured materials as well as to improve the understanding of their corrosion behaviour has gained much attention. However, studies on the corrosion behaviour of electrodeposited nanocrystalline materials are rather limited. Hence, the corrosion performance of nanostructured materials in various electrochemical conditions will be addressed here. This review will provide a survey of existing literature on corrosion behaviour of electrodeposited nanostructured pure metals and its alloys as well as composites.
