Abstract: A method is disclosed for repairing defects in a gas turbine component 10 that comprises a substrate 58 and an existing coating 44 on the substrate 58. The article 10 includes cooling holes 18 having a predetermined air flow requirement and an outer shaped portion 52 and an inner metering portion 60. The method comprises removing the existing coating 44 and recoating the surface of the article with a nonoriginal coating. After the nonoriginal coating is applied onto the component, the cooling holes 18 that meet a predetermined inspection criteria are reworked to remove the excess nonoriginal coating deposited in the outer shaped portion 52 of the cooling holes 18. The reworking is done by receiving an electrode 52, having only a shaped portion with a preselected shape, in the outer shaped portion 50 of the cooling holes 18 thus restoring the cooling holes to the predetermined air flow requirement.
