    Presented at PICALO 2006

    Laser Metal Deposition (LMD) is a validated process for repairing aero engine parts and complete components. An increase of the specific efficiency of aero engines is achieved by replacement of heavy parts out of Nickel Base Alloys in the HPC (High Pressure Compressor) and LPT (Low Pressure Turbine) sectors by lightweight parts out of TiAl Alloys in operating temperature ranges from 450 up to 700 °C. Due to the use of these upcoming new materials and n...
