Abstract

[Materials design and selection in aerospace industries are dictated mainly by the density, specific strength/stiffness in static and dynamic conditions, thermal and operating environment stability. Among the various classes of materials, metals and alloys are still a favourable choice by the aircraft/aeroengine designers because of their reliable performance, predictable properties and matured processing technologies. A persistent challenge in the metal and alloys is that they, in general, are prone to corrosion of one or various forms. Corrosion is inevitable in the long run in any airframe and aeroengine structures cutting down their life and, in severe cases if the corrosion is unnoticed, endangering the aircraft by causing catastrophic failure. Among various alloys, Mg and Al alloys are the first choice by the airframe designers due to their lightweight, high specific strength/stiffness, reasonably good fatigue and fracture toughness properties. Most structural alloys, especially the Mg and Al alloys, develop various forms of corrosion depending on the operating environment, load and temperature. Hence, it is imperative to understand the various forms of corrosion and analyse their corrosion behaviour as it also suggests effective measures for prevention of corrosion. This special publication addresses not only all the above aspects but also the basic outline for airworthiness-based concurrent alloy development with special emphasis on the latest technologies /methods available in the corrosion protection for these alloys in the aerospace industry.]
