Currently, aero-engine metallic components are manufactured by casting and forging processes, but the Laser Metal Deposition-Powder (LMDp) technique has gained much attention in repairing aero-engine components due to its flexibility and reliability in controlling various process parameters. The successful implementation of the LMDp process for Ti6Al4V repairs relies heavily on the characterization of the feedstock powders. This project FEEDER aims to provide a comprehensive feedstock characterization of Ti6Al4V powders for the LMDp additive manufacturing process. The influence of feedstock characteristics such as powder particle size, flowability, chemical composition, and surface morphology on the processability and resulting properties of Ti6Al4V additive manufactured parts and repairs will be investigated. This work will contribute to the optimization of the LMDp process parameters, especially in repairs in the aviation industry and the production of high-quality titanium components. Also, this project will lead to developing knowledge on setting the Ti6Al4V feedstock specifications and procurement for the LMDp process.
