Journal ArticleDOI
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.

A Unified Field Approach for Heat Conduction From Macro- to Micro-Scales
TL;DR: In this article, a universal constitutive equation between the heat flux vector and the temperature gradient is proposed to cover the fundamental behaviors of diffusion, wave, phonon-electron interactions, and pure phonon scattering.

Bonding mechanism in cold gas spraying
TL;DR: In this paper, a hypothesis for the bonding of particles in cold gas spraying, by making use of numerical modelling of the deformation during particle impact, is presented, with the results of modelling assessed with respect to the experimentally evaluated critical velocities, impact morphologies and strengths of coatings.

An analysis of the cold spray process and its coatings
TL;DR: In this paper, computational fluid dynamics (CFD) and extensive spray tests were performed for detailed analyses of the cold spray process, and the modeling of the gas and particle flow field for different nozzle geometries and process parameters in correlation with the results of the experiments reveal that adhesion only occurs when the powder particles exceed a critical impact velocity that is specific to the spray material.
