An innovative cold spray method for the deposition of ferromagnetic particles is presented. A magnetic field is used to magnetize and then accelerate the sprayed particles towards the substrate. In addition, the magnetic attraction focuses the trajectories of the particles so that their spreading is reduced. This magnetic assisted cold spray achieves higher deposition efficiencies in comparison with the conventional process. The quality of the produced coatings, as regard their porosity, is increased too. The proposed method shows promises of being a useful tool to expand the industrial applications of cold spray.
