Application: Method for manufacturing turbine component, method for repairing the same, and turbine component (Patent ID: US20230311212A1)
The patent filed by Toshiba Corp. describes a method for manufacturing a turbine component using a seed crystal and shaped layers. The method involves placing the seed crystal on the base surface in a specific orientation and then forming the shaped layers by scanning with an energy beam. The seed crystal, a single crystal, is a metal with a face-centered cubic crystal structure or an L12 phase. The scanning direction during the shaped layer forming step is crucial, with specific angles required in relation to the orientation of the seed crystal.
Furthermore, the patent includes various claims related to the manufacturing process, such as specific angle requirements for the seed crystal placement and scanning direction, the use of a nickel-based alloy for the powder material, and the use of a laser beam as the energy beam. The method also allows for repairing turbine components by following a similar process of seed crystal placement and shaped layer formation. Overall, the patent aims to simplify the manufacturing process of turbine components by utilizing a seed crystal and precise scanning techniques to achieve a single crystal structure efficiently.
