Problems solved by technology

However, these post-casting modifications are limited, and in view of the increasing complexity of turbine engines, and the recognized efficiency of certain cooling circuits within turbine blades, necessitate requirements for more complex and intricate internal geometries
While investment casting is capable of making these parts, positioning accuracy and intricate internal geometries complicate manufacturing with these conventional manufacturing processes

Abstract

The present disclosure generally relates to casting with metal components and metal skin layers. The present disclosure generally relates to casting molds including a casting core comprising an outer shell mold surrounding at least a portion of a casting core and a casting core comprising a second metal skin layer around a first metal component. In one aspect, at least one portion of the first metal component may be exposed on a surface of the outer shell mold. In another aspect, the outer shell mold may be configured to define a cavity in the casting core when the first metal component is removed and the second metal skin layer is not removed.

Description

technical field [0001] The present disclosure relates generally to casting core components and processes utilizing these core components. The core part of the present invention may comprise a metal skin layer surrounding a first metal part having a lower melting point than the metal skin layer. Metal skin layers and metal parts provide useful properties in foundry operations, such as superstructures used to produce turbine blades, near-wall cavities of turbine blades, or cooling cavities of turbine blades for jet aircraft engines or power generation turbine components. Alloy casting. Background technique [0002] Many modern engines and next-generation turbine engines require components and components with intricate geometries, requiring novel materials and manufacturing techniques. Conventional techniques used to manufacture engine parts and components include the painstaking investment casting process or lost wax casting process. An example of investment casting involve...
