Abstract (en)

A turbine component consists essentially of an electron conductive substrate (1) and a solid ion conductive electrolyte (2). The electrolyte (2) is coated with an electron conductive electrode (3) and the substrate (1) is electrically connected with the electrode (3) through a DC supply (11). The substrate serves as cathode and the electrode as anode. In a method to control the oxidation of a turbine component which consists essentially of an electron conductive substrate (1) and a solid ion conductive electrolyte (2), the formation of the substrate oxide (7) is controlled by the voltage of an adjustable DC supply dependent on the temperature of the turbine component and dependent on the oxygen partial pressure of the environment. <IMAGE>
