Method of manufacturing a bimetallic turbine blade and use thereof |
摘要 |
A receiving cavity having a simple geometrical shape is machined in a metallic block having a simple geometrical shape made of a first metallic material. A member made of the second material is made and fixed into the cavity to produce a composite bimetallic block, and the turbine blade is machined from the composite block, the body of the blade being machined from the metallic block made of the first material and the insert being machined from the member of simple shape made of the second material. The member made of the second material can be prefabricated and welded into the cavity of made by depositing and solidifying a molten metal in the cavity. The invention applies in particular to manufacturing a blade of a low-pressure stage of a steam turbine.
