Internal turbine component electroplating

A method of electroplating a surface area of a cooling cavity present in a gas turbine airfoil component, comprising positioning a flexible electroplating mask water-tight on an end region of the airfoil component where the cooling cavity has an open end to the exterior in order to mask that end region from being electroplated while the component is submerged in an electroplating solution, extending an anode through the mask and the open end into the cooling cavity, extending a cathode through the mask to contact the end region of the component, providing an electroplating solution supply conduit or passage through the mask communicated to the open end to supply the electroplating solution to the cooling cavity while the component is submerged in the electroplating solution, submerging the component in the electroplating solution, and electroplating the surface area of the cooling cavity of the component.
