Abstract
A method for adjusting the size of cooling holes of a gas turbine component is disclosed in which the component is shielded with an easily removable and non- conductive shielding material without shielding the cooling holes themselves. The cooling holes are then coated by a galvanic process and the size of the cooling holes is restored to within manufacturing tolerances. The shielding material is removed and, subsequently, a heat treatment for securing a bonding of the metallic coating is applied.
