Material Perspective and Deformation Pattern of Micro-sized Metallic Particle Using Cold Gas Dynamic Spray

The cold gas dynamic spray is a solid powder deposition phenomenon of coating and repairing with a broad materials range. This deposition technology gained attention not only in institutions but also in industrial aspects. This coating technology is a surface engineering technology which is presently replacing electron, laser beam type of technologies for additive manufacturing. This study provides the pattern of deformation of both particle and substrate under the impact of high particle velocity. An ABAQUS/Explicit, a finite element methodology was used to forecast the coating behaviour of different engineering materials. A FEM approach was used for the simulation of the metallic impact of substrate and particle. A wide range of impact velocities was used to finding the threshold or critical velocity for the proper deposition, phenomenon of rebounding and also to divulge the mechanism of governance, i.e. adiabatic shear instability (ASI). This study focused and revealed how engineering materials that are commonly used in aerospace engineering behaved under different impact conditions using kinetic spray coating technology.
