Abstract: A component for high-temperature use comprises a metallic base material and a non-ferromagnetic protective layer arranged thereon, which is able to form a protective oxide layer on the component surface at temperatures between 600° C. and 1100° C. A sensor material is introduced into the protective layer, wherein, in the stated temperature range, the local magnetism, notably ferromagnetism or ferrimagnetism, at the site of the sensor material is dependent on the local concentration and/or composition of the material of the protective layer in the immediate vicinity of the sensor material and/or on the cumulative temperature-time curve at the site of the sensor material. The component can be examined non-destructively, from the outside, for the local magnetism in the protective layer, which is typically between 100 ?m and 500 ?m thick.
