Abstract

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