Технології отримання теплозахисних по-криттів для лопаток газотурбінних двигунів

This article examines technolo-gies for producing thermal barrier coatings for gas turbines with the aim of improving their ef-ficiency and operational longevity. Optimal pa-rameters are estalished for various types of coatings, including the design and component composition of individual layers. The article describes laboratory and indutrial electron-beam units used for coating depostion, which provide optimal conditions for material pro-cessing and melting. The technical features of these units, their construction, and their ap-plicability for depositing different types of coat-ings are highlighted. Special attention is given to the latest L-9 unit, which differs from its pre-decessors by employing a cold cathode for elec-tron-beam heaters, thereby increasing their sta-bility and service life. The article also presents information on the control systems of the units and the operating principle of the L-9 unit, which can be used for depositing various types of protective coatings, including new micro-layered silicide coatings.
