Scientists from Tomsk State University of Control Systems and Radioelectronics (TUSUR) have created a prototype technological installation for electron beam deposition of thermal barrier ceramic coatings on gas turbine engine blades. This was reported by the press service of the educational institution.
One of the advantages of the domestic development is its compactness; foreign counterparts are larger. Due to this, electricity consumption is reduced, and the production cost is lower. The installation occupies only 20 square meters.
TUSUR scientists have applied forevacuum plasma electron sources. With their help, the electron beam directly affects the non-conductive ceramics.
In the coating process, two electron sources are used: one heats the blade to the required temperature, and the second evaporates the ceramic, creating the coating.
Currently, the installation is operating at 70% of its capacity. In the near future, it is planned to install additional pumps and power supplies, which will allow reaching full capacity.
