Abstract
A test component coated with a coating system is provided. In at least one defined region of the test component, there is a delamination having defined properties deliberately introduced into the coating system. The test component may be employed in a method for testing a thermography apparatus that is designed for carrying out a thermography method, for its correct operation with a view to the detection of delaminations. In order to test the thermography apparatus, the at least one defined delamination of the coating system is detected on the test component by using the thermography method employed in the thermography apparatus.
Claims10
A method for producing a test component having a metallic substrate that is to be coated with a coating system, the coating system including a bond coat and a thermal barrier coating, the method comprising:
- applying a localized auxiliary layer directly on the metallic substrate, wherein the auxiliary layer is a first ceramic layer,
- applying the bond coat as a metallic layer after having applied the localized auxiliary layer, and
- applying the thermal barrier coating as a second ceramic layer over the metallic bond coat,
- wherein applying the localized auxiliary layer deliberately produces, on a surface of the test component, at least one region comprising a defined delamination of the coating system.
A test component, comprising:
- a metallic substrate,
- a localized auxiliary layer applied directly the metallic substrate, wherein the auxiliary layer comprises a first ceramic layer, and
- a coating system, comprising:
- a bond coat comprising a metallic layer which is applied after having applied the localized auxiliary layer, and
- a thermal barrier coating comprising a second ceramic layer which is applied over the metallic bond coat,
- wherein a delamination is introduced into the coating system by way of the localized auxiliary layer, with defined properties in at least one defined region of the test component.
