PROFIL. It is a french national project initiated by a large group of industrial partners in the aerospace field (SNECMA moteurs, Dassault Aviation, EADS, Eurocopter, MBDA), two research centers (ENSMP and GERAILP) and one SME (Phénix Systems). The goal of the project is really dual : manufacturing aerospace parts in TA6V or Inconel718, for civil of military applications, by laser cladding of laser sintering. Morevoer, it is exepected to produce parts with good material properties, good dimensions and good surface roughness. The article presents the results obtained by the two techniques during the first two years of the project. The results can be decomposed into different topics : the systems and machines, the powder distribution and nozzles (for laser cladding), the process control, the parameter search and the metallurgical analysis, and, finally, the simulation process (laser cladding only).
