N2 - In the present investigation, Al5056 alloy-based metal matrix composites having SiC particles of different sizes were prepared by cold spraying. The average particle sizes of the used SiC feedstock varied from 66.94μm to 1.64μm. The calculated results by the FLUENT software show that the velocity of SiC particle decreases with the increase of the particle size, while the kinetic energy is greatly increased with increasing the particle size. The addition of SiC particles effectively reduces the porosity of the composite coatings. Furthermore, the porosity of the composite coatings increases with the decrease of SiC particle size, while the content of SiC in the coatings decreases with the decrease of SiC size. In addition, two effects of SiC particles determine the coating properties, i.e., the advantageous peening effect and the disadvantageous effect that reduces the effective contact between the coating and substrate.
