This abstract first appeared for US patent application 20240410290 titled 'METHOD FOR MANUFACTURING TURBINE LABYRINTH SEAL USING WIRE ARC ADDITIVE MANUFACTURING
Original Abstract Submitted
the present invention relates to a method for manufacturing a labyrinth seal using wire arc additive manufacturing, which is mounted between a diaphragm of a turbine and a turbine rotor to induce a smooth rotation of the turbine rotor and preventing gas leakage by minimizing friction between the diaphragm of a turbine and a turbine rotor when a rotating body such as the turbine rotor rotates inside a fixed body such as the diaphragm, and which includes a ring-shaped body part and a tooth part protruding on one side of the ring-shaped body part, wherein the labyrinth seal is deposition-manufactured by 3d printing, the body part is manufactured by the wire arc additive manufacturing, and the tooth part is manufactured by a directed energy deposition.
