Electrodeposited Metallic/ Nanocomposite Coatings

Abstract

Magnesium (Mg) alloys have emerged as the lightest structural material with attractive mechanical properties in combination with other characteristics of good biocompatibility, easy recyclability, large hydrogen storage capacity, high theoretical specific capacity, etc. The ever-increasing trend in the number of publications on Mg and Mg alloys in the past two decades indicates that the research interest on Mg alloys is attaining more and more attention. However, the inferior corrosion resistance is still persisting as a major bottleneck towards their wide practical application. Although there are different strategies to improve the corrosion resistance of Mg alloys, surface coatings attract a lot of attention, since the coatings improve corrosion resistance along with enhancement of other characteristics such as wear resistance, antibacterial activity, hydrophobicity, decorative appeal, etc. Among the various methods available for the development of surface coatings, electrode position is known to be a simple and efficient method for the deposition of coatings at ambient temperature with tuned characteristics and great degree of reproducibility. The chapter presents a concise discussion on the different types of electrodeposited coatings for their corrosion protection. © 2024 selection and editorial matter, Viswanathan S. Saji.
