Cold Spray Coating Deposition

The ever increasing research of lightness, improved performance, safety and reliability is pushing to look for materials with superior mechanical properties and to meet severe design requirements imposed in many fields of application, in order to obtain competitive products. Nanocrystal (NC) materials are experiencing a rapid development in recent years due to their existing and potential applications in a wide variety of technological areas; Cold Spray coating is an innovative deposition technique which uses elements of both physical deposition and severe plastic deformation for generating NC. CS is an emerging coating process in which, in contrast to other well-known thermal spray processes such as flame, arc, and plasma spraying, powders do not melt before impacting the substrate. Bonding of particles to the substrate occurs due to the high kinetic energy upon impact.
