TURBOMACHINE COMPONENT MARKING

摘要

The present invention describes a system (100) for indicating wear of a turbomachine. The system (100) comprises a turbomachine component (110), an indicating layer (202) which is formed on the surface of the turbomachine component (110), and a top layer (201) which covers the indicating layer (202), such that the indicating layer (202) becomes optically detectable if the top layer (201) is worn out by wear due to exposure of a working fluid or is fretted by fretting due to a contact of the turbomachine component (110) with a further turbomachine component (120).
