The main coating systems used in aerospace gas turbine engines are presented. Coatings are fundamental to protect the surface of the structural components from several degradation factors, like oxidation, corrosion, wear, and erosion. The complexity of the environments and servicing conditions of gas turbine engines requires properties and materials performances that can be attained only through the deposition on structural components and hot parts of composite coating systems. Several of them involve metallic layers, although it is just thanks to a suitable combination of diverse materials, featuring altogether the full range of needed properties, that an effective part protection can be assured. Temperature, as usual, is paramount, since it determines the kinetics of all relevant transformations. Therefore, thermal barrier ceramic coatings are included in this chapter, since they are fundamental for lowering the temperature in the underlying metallic component. Still, the underlayer of a thermal barrier coating, the so-called bond coat, is metallic, and it is paramount as far as an adequate resistance to high-temperature corrosion phenomena is concerned. The main deposition techniques, whose selection is crucial for obtaining a good quality control and durability of the coating systems, are also introduced.
