Effect of heat treatment on the microstructure and corrosion performance of 2219 Al alloy cold sprayed coatings
This study investigates the influence of different heat treatment conditions on the microstructure and corrosion performance of cold-sprayed coatings on 2219 Al alloy. The results indicate that heat treatment aging effectively improves plastic deformation within the coatings. The direct aging promotes grain refinement, optimization of misorientation angles, which effectively resist the penetration of corrosive media. The coating corrosion initially manifests as pitting corrosion, where interconnected pits lead to particle exposure, initiating intergranular corrosion, and eventually evolving into exfoliation corrosion. The corrosion resistance ranking is as follows: direct aging coatings > solution aging coatings > room temperature coatings > base material.
