    摘要: The subject of the invention is a method for repairing sealing surfaces of seal segments, arranged on the inner circumference of a turbine casing section, of a rotor/stator seal of a gas turbine. With the method according to the invention, first of all material is removed from the sealing surfaces of the seal segments with the exception of the base material of the seal segments, a metallic reinforcing coating with a material thickness of at least 1 mm is applied, and then a ceramic coating with a material thickness of 0.3 to 2 mm is applied to it.
