The corrosion of AA 7075-T6 aluminum alloy is a critical issue for many industries. In this study, aluminum coatings were deposited onto AA 7075-T6 by cold gas spray and the effect of the porous outer layer on different properties of the coating, including corrosion-resistance was investigated. As-prepared and polished samples were used to study the microstructure, morphology, mechanical properties and corrosion resistance of the coating in 3.5 wt.% NaCl solution. Cross-sectional analysis showed a dense structure, low porosity (0.8%) and thickness up to 300 lm (* 100 lm for the porous outer layer and * 200 lm for the compact inner layer). The sliding wear test resulted in a volume loss of 3.2 9 10 -4 mm 3 /Nm with an adhesive wear mechanism. The abrasive wear test showed a wear rate of 1.1 9 10 -4 mm 3 /Nm for the asprepared coating and 0.8 9 10 -4 mm 3 /Nm for the polished coating. The as-prepared coating pores and interparticle spacing in the outer layer were mostly responsible for the increase in wear rate. For the polished coating immersed in 3.5 wt.% NaCl solution during 900 h, the electrolyte reached some specific points of the substrate as revealed by the cross-sectional analysis. Inspection of the as-prepared coating demonstrated that the coating/substrate interface was completely damaged after long immersion times (* 900 h).

“…It was also reported that the bonding strength of the composite deposit was related to the morphology of ceramic particles [106,139]. Generally, spherical ceramic particles were more efficient in enhancing the deposit bonding strength than angular ceramic particles [136].…”

“…22, the porosity of the SiC/5056Al composite deposit decreased slightly with the increase of ceramic particle size. According to Qiu et al [106], the spherical ceramic particles were more efficient for reducing the porosity compared to irregularly shaped particles due to the enhanced in-situ peening effect of the spherical powders.…”
