Non-Destructive Characterization of Coating and Material Conditions of Severely Stressed Turbine Components (A01)

• Subject Area: Coating and Surface Technology ; Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2010 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 119193472

In order to plan and budget necessary repairs of aero-engine components at an early stage, the development of electromagnetic and thermographic testing methods that allow for a fast fault detection and material characterization of the turbine- and compressor-blades (rotor and stator) already in a partially disassembled state of the engine are intended. The application of newly-developed repair technologies leads to unknown changes of the repaired components mechanical properties. Therefore, the development of a test rig for the non-destructive online detection and characterization of the damage evolution under thermal and cyclical loads is also intended.
