More Information
Summary:A method for manufacturing a turbine blade (1) is provided. The method comprises the following steps: producing a shell and core assembly by additive manufacturing process, the shell and core assemblydefining at least one internal cavity and having an internal structure corresponding to at least one internal cooling circuit of the turbine blade; pouring molten metal in the internal cavity of theshell and core assembly; solidifying the metal; removing the shell and core assembly. 本发明提供了种制造涡轮叶片(1)的方法。所述方法包括以下步骤：-通过增材制造过程产生壳体和核心组件，所述壳体和核心组件限定至少个内部空腔并具有与所述涡轮叶片的至少个内部冷却回路对应的内部结构；-在所述壳体和核心组件的所述内部空腔中倒入熔化金属；-使所述金属凝固；-去除所述壳体和核心组件。
