Method for the manufacture of a turbine blade with an oxide layer on a metallic coating, a turbine blade and its use, and a method for the operation of a turbine.

摘要

The method for producing a turbine blade (110, 130, 155) for the third and/or fourth stage of a gas turbine, where the blade has a substrate (4) with an oxide on a metallic layer (7), comprises oxidizing the metallic layer at 1000[deg] C in nitrogen, argon and/or helium using water vapor, and optionally applying a ceramic heat-insulating layer (13) on the metallic layer. The oxidation of the metallic layer is carried out in vacuum or with an oxygen partial pressure of 10 - 7 to 10 - 1 5. Independent claims are included for: (1) turbine; and (2) procedure for the operation of a turbine.
