Abstract
The subject matter of the invention is a component which is provided with a ceramic coating forming the surface. Inventively there is provision at least in a cover layer of the coating for nanoparticles made from a colorant (CrCoAl or a spinel-type oxide) and aluminum oxide nanoparticles. This combination of nanoparticles in the coating advantageously results in a resistance to high temperatures of the coloring of the surface of up to 1000° C. not previously known. This allows even components under great stress, such as for example compressor or turbine blades of a gas turbine, to be provided with temperature-resistant coloring. This can then be used for an optical inspection for example. Protection is also claimed for a method for creating the inventive coating.
