Abstract: A process for coating an edge within a hole in a coated component is provided. The hole is a cooling-air hole operable conduct a coolant therethrough. According to the processes, an outer coating is provided on the outer surface of the component. An inner coating is provided on an inner surface within the hole, wherein the inner coating within the hole takes place using a coating nozzle at a different angle to the coating of the outer surface around the hole, if the spray angles for the outer coating and inner coating relate to the outer surface.

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.

Abstract: A method for coating a substrate of a component is provided. Using the previous coating method, localized coating that can occur unexpectedly at one spot is often more difficult because the coating sequence must be reprogrammed here. This irregularity is resolved in a short period of time by a simple, manual coating.
