Abstract
The invention relates to a coated turbine component adapted for exposure to a hot gas flow, comprising a component body comprising a base material, a thermal barrier coating applied to the base material, and a thermographic phosphor arranged within, on or beneath the thermal barrier coating surface adapted to emit light corresponding to a temperature of the thermographic phosphor. The invention also relates to a method for producing a coated turbine component comprising applying a first thermal barrier coating containing an activator to a component body base material, the activator providing the thermal barrier layer coating with thermographic properties such that light is emitted corresponding to a temperature of the thermographic phosphor, applying a second thermal barrier coating that does not contain the activator on top of the first thermal barrier coating, and removing a portion of the second thermal barrier coating to expose the thermographic phosphor layer underlying the second thermal barrier coating. The invention also relates to a method for producing a coated turbine component comprising applying a thermal barrier coating to a component body, trenching the thermal barrier coating to form a base at the bottom of the trench and applying a thermographic phosphor to the base of the trench.
