Cold spraying of light alloys

Cold spraying (CS) is a very promising technology for the manufacture of coatings and composites, the spray-forming of near-net components, and the surface protection of materials. This chapter overviews the applications of cold spraying technology for such light alloys as Ti, Al and Mg alloys. The microstructure and properties of cold-sprayed coatings of these alloys depend on the nature of the coating materials in terms of density, strength and activity. The processing parameters must be carefully adjusted to produce the expected coating for the required application. Finally, surface protection of light alloys by the cold spraying technology is also discussed.
