Abstract
A Method for modifying a plurality of cooling holes of a turbine component includes disposing a recess-shaped modification in a recess of the component comprising a plurality of cooling hole outlets, wherein the recess-shaped modification is formed to substantially fill the recess and comprising a plurality of modified cooling holes passing there through. 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, inserting at least one alignment pin into at least one of aligned pair of holes and hole outlets, bonding the recess-shaped modification disposed in the recess to the component, and removing the at least one alignment pin after bonding, wherein the plurality of modified cooling holes of the recess-shaped modification is fluidly connected with the plurality of cooling holes of the component.
