Purpose. Application of protective anti-erosion and anti-corrosion coatings on the rotor blades of the last stages of turbines of thermal and nuclear power plants to improve reliability and efficiency in turbine operation.
Specifications.
- Coating methods: electron beam evaporation; atomic ion sputtering.
- Electron beam current, µA 1-1000
- Electron energy, keV 60
- Vacuum in the chamber, Pa 10–4
- Power consumption, kW 1-60.
Field of study. Energy (thermal and nuclear power plants).
Advantages. In contrast to traditional technologies for strengthening steam turbine rotor blades, such as soldering stellite plates or applying high-hard coatings in an air atmosphere, an installation was developed and a technology was proposed for applying a two-layer anti-erosion and anti-corrosion coating in vacuum on the blades of the last stages of low-pressure cylinders. 25-30%) increase their resource.
