Abstract: A flow element for fluidic contact with a hot gas flow inside an aircraft engine includes: a base material, which has a hot gas surface that faces the gas flow and a remote surface that is remote from the gas flow, the base material being completely surrounded by a chroming layer on the hot gas surface and on the remote surface; an adhesive layer on the chroming layer in first portions; an alitising layer, the alitising layer being arranged on the adhesive layer in the first portions; and a thermal barrier layer being arranged on the alitising layer in the first portions. The alitising layer is arranged on the chroming layer in second portions that do not have an adhesive layer, the chroming layer and the alitising layer forming a chroming-alitising layer in the second portions.

Abstract: 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.
