| Abstract | Cold Spray is an emerging thermal spray technology where powders are accelerated at supersonic velocities onto the surface to be coated, whereupon they consolidate and bond instantly on impact. This manufacturing process can produce few microns to several centimeters’ thick deposits from a variety of materials displaying a wide range of properties. This paper presents several case studies to illustrate how cold spray flexibility can lead to several promising applications within the transportation industry. Firstly, as a coating process, it can enhance performance of light metals. The specific example of a bilayer steel-based coating for the production of lightweight Al brake rotor discs that show unmatched adhesion and thermal cycling resistance with wear and frictional performance equivalent to cast iron will be presented. As an additive manufacturing method, it will be shown that cold spray can build topologically optimized structural reinforcement on large aluminum panels for surface transportation. Finally, as a localized metal addition technique, its capability to add transition layers to allow the welding of dissimilar materials will be demonstrated for the friction stir welding of aluminum and high strength steel. |
