Hybrid and electric vehicles play an increasing role to alleviate the effects of our transportation needs on the environment. Permanent magnets are a key component of electric motors and represent a significant proportion of their total cost. We report on the fabrication of metal-NdFeB composite permanent magnets made using cold spray processes. In order to control the magnetic properties, coatings’ microstructure was varied using powders with various compositions, size distributions and morphologies. The obtained magnetic and mechanical properties results confirm the feasibility of using cold spray as an effective technology to deposit hard magnet coatings directly on the rotor surface.
