Methods of increasing the service life of gas turbine engine turbine blades
Аннотация
The article discusses methods for increasing the service life of turbine blades of gas turbine engines (GTE). These blades are important components operating at high temperatures and loads, and various technologies are used to increase their durability. The main methods include the application of hardening coatings, the use of new heat-resistant materials, and chemical and physical coating technologies. In the aviation industry, the issues of improving the efficiency of aircraft engines and their long-term operation are of significant importance. The service life of each aviation engine, its maintenance, and operational costs primarily depend on the strength of its main components. This is especially true for turbine blades, which are among the most loaded parts of a gas turbine engine, as they operate under extreme temperature and stress conditions. At temperatures of 1500°C and above, the blades can be subjected to deformation or damage due to high thermal and mechanical stresses. Methods such as PVD and CVD are used to apply high-temperature and corrosion-resistant coatings to the surface of the blades, which ensures their long-term and efficient operation. The article also provides detailed information on the advantages of these coating technologies and their impact on turbine components.
