Plasma Electrolytic Oxidation Coatings on Aluminum Alloys: Microstructures, Properties, and Applications Material Science The aerospace industry demands that the materials used for making aircrafts meet the required specifications of increased resistance to fatigue and corrosion, improved fracture toughness, and have high strength-to-weight ratio because of their condition of service [1,2]. Aluminum and its alloys have been the primary choice of materials in the aerospace industry since the late 1920s. Today they constitute about 70-80% of many modern aircrafts due to their high strength-to-weight ratio, easy workability, and low prices [3-6]. For example, aircrafts such as Airbus A340/A330 and Boeing 757 have their major components and load bearing structures made of aluminum alloys [7]. Although polymer composites have emerged as competitive materials in the manufacturing of aircrafts, aluminum and its alloys remain the most widely used materials in the aircraft indust...
