Purpose of the development: Examples of use: • Turbine Turbocharger • Impeller gas turbines • Details of the internal combustion engine: - The head of the piston - Cylinder liner - The head of the cylinder block - Cranks • The components of metallurgical equipment

Recommended application field: The new material is intended for use in high temperature and / or corrosive environment

Technical characteristic: Cermet material properties (cast) Maximum operating temperature, ° C 780 Density, g/cm3 4600 Hardness range, MPa / Elongation,% 20 ° 980/0, 2 300 ° 775/0, 3 600 ° C 681/0, 5 800 ° 314/24 Yield compression, MPa 1650 Relative Compression Set,% 5.2 Crack resistance MPa/m12 20 Hardness, HRc 43 ... 45 Young's modulus, GPa 141 ... 146 Thermal conductivity, W / (mK) 5.9 ... 7.0 Koefitsient thermal expansion in the range of 20 ... 800 ° C x10-6 / ° C 8.5 ... 10.0

Advantages over analogues: Product advantages: • Increased operating temperature • High fracture toughness • Low density • Low thermal conductivity • Resistance to high-temperature gas corrosion Advantages of the technology: • Casting • Forging • Powder Metallurgy • High workability • The cost of production is lower than that of ceramic materials

The development stage readiness: Ready for application

Description of the development:
()
National Metallurgical Academy of Ukraine can organize the production of prototypes of components for the experimental evaluation. Prototypes can be made according to technical drawings by casting or forging in the forms and stamps provided by the customer Other conditions may be the subject of negotiations. A large number of CERMET-composite materials have been developed in NMetAU These materials were identified by two major families of alloys, of which one has a better high-temperature strength, the other - the best oxidation resistance These materials are clearly better than any ceramics, suitable for the engine
