Which is better for cold spraying zinc plating?

In this project, East China zinc shield is used for cold spraying zinc coating. Ten years later, the anti-corrosion effect is still good. Before using zinc cover to repair, the original steel structure has faded and pulverized seriously; The repaired steel structure is protected by cold spraying zinc with zinc cover, which forms a protective barrier, effectively prolongs the service life, saves us a lot of repair costs in the past ten years, and greatly improves the cost performance. Moreover, the zinc shield can be used as a single layer, or it can form a two-layer or three-layer supporting system with sealing paint, topcoat and zinc-aluminum coating to meet the needs of long-term protection and aesthetic decoration of our project. If anti-corrosion is needed, you can also try cold spraying zinc with zinc shield.
