L-2 Installation designed for:
- re-melting of metals and alloys for refining and producing of cylinder-shaped ingots;
- combined melting of ingots of different initial metals in order to derive pure alloys, including intermetallide alloys, such as Ni3AI, TiAl;
- evaporation and depositing protective and structural (thick) metal, ceramic-metal, and ceramic coatings on flat surfaces and surfaces of the body-of-revolution type, including gas turbine blades;
- synthesis in the process of phisical vapour deposition of various substances, refractory compounds, (carbides, cilicides, borides) and intermetallides, and generating thin and thick coatings;
- obtaining of dispersion dispersion-strengthened, microlayered and microporous materials in the form of coatings and massive substrate-detachable ingots;
- obtaining of thin and thick coatings from superconductor ceramics;
- obtaining of coatings from carbon non-equilibrium phase.
