METHODS FOR MODIFYING COOLING HOLES WITH RECESS-SHAPED MODIFICATIONS, AND COMPONENTS INCORPORATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide modification of cooling holes of a turbine component.SOLUTION: Methods for modifying a plurality of cooling holes of a component include disposing a recess-shaped modification in a recess 20 of the component comprising a plurality of cooling hole outlets, where the recess-shaped modification is formed to substantially fill the recess and comprises a plurality of modified cooling holes passing therethrough. The method further includes aligning the plurality of modified cooling holes of the recess-shaped modification with the plurality of cooling hole outlets of the component, and, bonding the recess-shaped modification disposed in the recess to the component, where the plurality of modified cooling holes of the recess-shaped modification is fluidly connected with the plurality of cooling holes of the component.
