Cold spray as a coating deposition technology based on high-speed impact dynamics has thrived withconsiderable capabilities. In this process, sprayed particles are accelerated to a high velocity by a highspeedgas flow that is generated through a convergent-divergent de Laval type nozzle. A deposition isformed through the intensive plastic deformation of particles impacting on a substrate at a temperaturebelow the melting point of the sprayed material. One of its key applications is the recovery of costly aircraftparts during the overhaul and repair. This process is used for providing surface modification or wearresistance to a substrate, depositing thermal barrier coatings and many other applications without theundesirable effects of process temperatures or metallurgical incompatibilities. This article presents thefindings of a comprehensive state-of-the-art literature review of the scientific and technological progress ofthis technology in the field of repair using the concept of additive manufacturing.
