TURBO ENGINE COMPONENTS REPAIR METHODOLOGY BY LASER MATERIAL DEPOSITION

Abstract

Additive Manufacturing (AM) is an on growing technology in the last decade. Aeronautical industry, among others, is getting involved in this new trend for manufacturing and repairing processes. More concrete inside AM techniques, Laser Metal Deposition (LMD) is a versatile process with the capability of any repairing task, though the use of this technology is considered a multidisciplinary process that requires knowledge of several aspects: 3D digitalization, CAD/CAM programming, and the laser cladding parameters and control. Considering these many challenges, this work states a global vision through all process stages in order to implement LMD repairing technology in several industries. Additionally, trials were performed related to different process stages with significant results serving as initial reference for turbomachinery rotary components repairs. Finally, advantages and drawbacks of LMD process, as well as industrial pioneering companies at this sector. Keywords: Turbomachinery reparation, LMD (Laser Material Deposition), Digitalization, 3D, CAD/CAM, laser cladding, Inconel 718, Hastelloy X, hybrid machines.
