The particle impact results in the generation of high stresses and strains both in the particles and the substrate. As shown in the basic monographs (Champagne, 2007; Papyrin et al., 2007), the powder material to be sprayed must feature sufficient ductility to ensure particle strains and cold welding without its failure. In some cases (at very high particle velocities) Ti alloy particle melting occurs (Vlcek et al., 2002). However, impact of other metallic powder materials is characterized by high stresses and particle shear strains. Because a lot of information is available on various powders and powder mixtures developed and applied for cold spraying (Jeandin et al., 2014; Moridi et al., 2014, and others), the goal of this chapter is to describe and discuss the concept of CS material selection, basic criteria for evaluation of its suitability for cold spraying, and particle behavior during the deposition process (acceleration and formation of interfaces), Book chapter, Paolo Matteazzi , Alberto Colella , Volf Leshchynsky , Kazuhiko Sakaki et al.
