Disclosed is a turbomachine having an annular flow duct and a housing structure surrounding the flow duct and a multiplicity of guide vanes and rotor blades which are arranged in the flow duct. The rotor blades are rotatably accommodated in the housing structure whereas the guide vanes are fixed in the housing structure, a plurality of guide vanes forming an annular guide vane ring. The housing structure has a seal in the region of the radially inner flow duct boundary in order to prevent hot gas escaping from the flow duct, which seal is arranged on guide vane roots of the guide vanes of the guide vane ring via a seal support and forms a seal against a rotatable seal surface, the seal support being formed from an intermetallic material, in particular a TiAl material.
A turbomachine, wherein the turbomachine comprises an annular flow duct and a housing structure surrounding the flow duct and a multiplicity of guide vanes and rotor blades which are arranged in the flow duct, the rotor blades being rotatably accommodated in the housing structure and the guide vanes being fixed in the housing structure, and a plurality of guide vanes forming an annular guide vane ring, and wherein the housing structure has a seal in a region of a radially inner flow duct boundary to prevent hot gas escaping from the flow duct, said seal being arranged on guide vane roots of the guide vanes of the guide vane ring via a seal support and forming a seal against a rotatable seal surface, said seal support being formed from an intermetallic material.
A method for producing a seal support for a turbomachine, wherein the method comprises casting or forging a semi-finished product for the seal support from an intermetallic material, and thereafter removing edge zones of the semi-finished product entirely.
