Methods for the controlled reduction of turbine nozzle flow areas and turbine nozzle components having reduced flow areas

摘要

Embodiments of a method (10) for controllably reducing of the flow area of a turbine nozzle component (14) are provided, as are embodiments of turbine nozzle components (14) having reduced flow areas. In one embodiment, the method (10) includes the steps of obtaining (12) a turbine nozzle component (14) having a plurality of turbine nozzle flow paths (22) therethrough, positioning (42) braze preforms (30) in the plurality of turbine nozzle flow paths (22) and against a surface of the turbine nozzle component (14), and bonding (48) the braze preforms (30) to the turbine nozzle component (14) to achieve a controlled reduction in the flow area of the turbine nozzle flow paths (22).
