Abstract
Ferrous and nonferrous materials are the most substantial materials used in various industrial applications due to their entrancing properties, such as high toughness and high machinability. However, in many industrial applications, metal alloys exhibit weak corrosion and wear resistance behaviors compared to ceramics. To address the needs for improving corrosion and wear resistance of traditional materials in harsh conditions, ceramic coating is used. The ceramic coating is one of the efficient ways of enhancing the material's protective behaviors against abrasive and corrosive nature. These days, nanostructured ceramic coatings exhibit improved corrosion and wear resistance behaviors. The nanostructured materials are dominating the research interest as they acquire the synergetic properties of host materials. In recent years, metal oxide ceramic coatings like alumina, magnesium–lithium alloys, nickel-based composites, bio-based ceramic coatings, etc., have gained huge attention in developing anticorrosive and antiwear materials for aerospace, automotive, and electronics applications. In this chapter, ceramic materials used to improve the corrosion and wear resistance of traditional materials coated using plasma electrolytic oxidation are discussed.
