FIELD: manufacture of parts of gas turbines of super-alloys by investment pattern casting process.
SUBSTANCE: cores are made as composite ones from ceramic component and refractory metal component. The last is designed for enhancing mechanical properties of core and it may be bound with ceramic component by means of mechanical or chemical bonding. Refractory component may form outlet edge of core or its other members. Such core may form in wall of casting holes with diameter 0.3 mm.
EFFECT: possibility for making cores with shape and configuration unavailable for production in prior art techniques.
