United Engine Corporation (UEC)showed in a video the process of applying a thermal barrier coating to gas turbine engine blades using the electron-beam evaporation method.
Ceramic coating - yttria-stabilized zirconia (YSZ), allowing turbine blades to operate in a high-speed gas flow. To coat the blades with the thinnest layer of ceramic coating, the material is evaporated with a high-power electron beam, while the blades rotate in the resulting vapor.
The coating thickness does not exceed 0.15 mm - approximately 2-3 human hairs in cross-section. Coating the blades with yttria-stabilized zirconia improves the heat resistance of the parts.
This is necessary to maintain the integrity of the blades, as the gas flow temperature can reach 1800-2000 degrees Celsius, which exceeds the melting point of the metal from which the turbine blades are made.
