These engines, which power the vast majority of passenger aircraft, cargo jets and military fighter aircraft, are extremely reliant on state of the art coatings that improve their thermal protection, oxidation resistance and wear durability.
Ceramic coatings, aluminide coatings, and TBCs are applied to turbine blades, combustors, and afterburners by manufacturers to increase resistance of extreme temperatures and prevent premature engine failure. Additionally, the introduction of leading-edge ultra-high bypass ratio (UHBR) turbofan engines with their tighter design parameters has increased the need for coatings that enhance fuel efficiency and extend time between maintenance.
Turbojet engines typically operate in extreme environments (for example, in military fighter jets, reconnaissance aircraft, and supersonic transport systems) and so coatings for turbojet engines must resist high temperatures and extreme pressure and rapid acceleration conditions. The engines run under extreme thermal and mechanical stress and require protective coatings that improve oxidation resistance, erosion protection and thermal barrier performance.
For example, plasma-sprayed ceramic coatings and oxidation-resistant MCrAlY (Metal-Chromium-Aluminum-Yttrium) coatings are extensively used in turbojet engines to guarantee a prolonged component service life. Infrared emissions reduction coatings are also a key Military Stealth Tool, with defense contractors and engine manufacturers placing increased scrutiny on these coatings.
