Abstract
Electrolytic methods are used to treat large external surfaces. There is described a method for internally coating through-holes of a wall, wherein an electrolyte flows through the through-hole during the treatment and deposits material on the respective inner surface. A single electrode is being used for at least two through-holes.

-15. (canceled)
A process for an electrolytic treatment of a component having at least two through-holes, comprising:
- treating the through-holes on a inner surface;
- and
- using a single pole electrode having a plurality of projections for the through-holes, wherein the through-holes have an identical polarity, and wherein the projections project into the through-holes.
A turbine blade of a gas turbine, comprising:
- through-holes treated based upon an electrolytic treatment based upon an inner surface treatment by using a single pole electrode having projections for the through-holes, wherein the through-holes are film-cooling holes.
A process for the electrolytic treatment of a hollow blade of a turbomachine, comprising:
- providing the blade having through-holes in a leading edge;
- treating the through-holes on a inner surface based upon the electrolytic treatment;
- and
- using a single pole electrode having projections for the through-holes, wherein the through-holes have an identical polarity and the projections have an identical polarity.
