    摘要: Methods of manufacturing or repairing a turbine blade or vane are described. The airfoil portions of these turbine components are typically manufactured by casting in a ceramic mold, and a surface made up of the cast airfoil and at the least the ceramic core serves as a build surface for a subsequent process of additively manufacturing the tip portions. The build surface is created by removing a top portion of the airfoil and the core, or by placing an ultra-thin shim on top of the airfoil and the core. The overhang projected by the shim is subsequently removed. These methods are not limited to turbine engine applications, but can be applied to any metallic object that can benefit from casting and additive manufacturing processes. The present disclosure also relates to finished and intermediate products prepared by these methods.

    摘要: The disclosure relates to an apparatus for manufacturing a metallic component, and corresponding methods. The apparatus may include a build plate with a build surface and an aperture. The apparatus may also include an actuator operable to translate a metallic component such that an end portion of the metallic component is positioned within the aperture of the build plate and below the build surface. The apparatus may further include a seal coupled within the aperture of the build plate and configured to engage the end portion of the metallic component. The aperture of the build plate, the seal, and the end portion of the metallic component may cooperate to form a powder bed to hold metallic powder therein. The apparatus may also include an external heat control mechanism operable to form a predetermined temperature profile of the end portion of the component to prevent cracking of the component.
