TLDR
The use of cold spray for repair is often favored because, unlike thermal spray methods, cold spray does not bring about heat related damage to the component under repair as mentioned in this paper, which is often applied to coating applications but can be used for the repair of defects in and damage to metal structures.Abstract:
The deposition of material by cold spray is a relatively new technology. It is often applied to coating applications but can be used for the repair of defects in and damage to metal structures. The use of cold spray for repair is often favoured because, unlike thermal spray methods, cold spray does not bring about heat related damage to the component under repair. The status of the technology and the barriers to widespread commercial application are assessed. The types of repair that have been made with cold spray are discussed, and the unique features of cold spray that permit successful repairs are demonstrated.read more

Cold spray coating: review of material systems and future perspectives
TL;DR: In this article, cold gas dynamic spray or simply cold spray (CS) is a process in which solid powders are accelerated in a de Laval nozzle toward a substrate, and if the impact velocity exceeds a threshold value, particles endure plastic deformation and adhere to the surface.
