Friction-Stir Processing of a Cold Sprayed AA7075 Coating Layer on the AZ31B Substrate: Structural Homogeneity, Microstructures and Hardness

In this study, the cold gas dynamic spraying (CGDS) process was employed to modify the surface of AZ31B magnesium alloy with an aluminum-zinc alloy (AA7075). Friction-stir processing (FSP) was subsequently applied as a solid-state localized surface modification technique to improve the structure and...
