Abstract

Cold spray is a technology based on kinetic energy hater than thermal energy. It consists in shooting powders against a target at a velocity over a threshold value to get adhesion of the particles on the target material. Nowadays it is mainly used for coatings and repairs but it could be used also for manufacturing 3D free standing part, for additive manufacturing. However it is important to investigate the properties of parts obtained with cold spray before any ass In the presentation, after having introduced the basis of cold spray, the first results of mechanical tests carried out on Inconel samples obtained with cold spray are shown, discussed and compared with analogous samples obtained using SLM.
