AB - In this study, a multi-particle Eulerian model with finer meshing size was established by Python script in order to investigate the deposition process of metallic and MG coatings during cold spraying. The simulation results showed that the penetration depth of the substrate has connect with the strain hardening exponent and the pores existed at the particle boundaries shrunk as the preheating temperature rose. The qualitatively analysis about residual stress for the Cu/Cu combination at the interface between the coating and substrate was tensile, which was consistent with the previous study. For the MG coatings, particles experienced inhomogeneous deformation and attached loosely at lower preheating temperatures. But homogeneous deformation emerged at higher preheating temperatures and the coatings became dense. Hard substrates were preferred when preparing MG coatings. Differences between the metallic coatings and MG coatings during the coating formation were mainly attributed to four aspects: the purpose of preheating, the deformation mechanism, the determination of spraying parameters and the selection of substrates.
