High zinc layer is a common anti-corrosion technology, its main function is to extend the service life of the metal surface, reduce oxidation corrosion. This paper will introduce the principle, production method and application field of high zinc layer.

High zinc layer is a kind of anti-corrosion technology which is coated with a layer rich in zinc on the metal surface, which is mainly used to prevent metal oxidation corrosion. Zinc has excellent barrier and electrochemical stability, and can form a protective film to block direct contact between oxygen and metal, thereby extending the service life of metal.
The method of producing high zinc layer includes hot galvanizing, electro galvanizing, spraying zinc and other technologies. Hot-dip galvanizing is one of the most common methods, which obtains a high-zinc layer with high corrosion resistance by dipping a molten zinc coating on the metal surface. Electrogalvanizing is to soak the metal in a zinc-containing electrolyte, and use the current to deposit zinc on the metal surface to form a zinc layer.
High zinc layer is widely used in construction, automobile, ship and other metal products. In terms of construction, the high-zinc layer can effectively prevent metal components from being corroded by the atmosphere and moisture, and extend the service life of the building; in automobile manufacturing, the high-zinc layer can protect the surface of the body from environmental effects such as salt spray and acid rain; in the field of ships, The high-zinc layer can prevent seawater corrosion and ensure the stability of the hull structure.
In general, as an important anti-corrosion technology, high-zinc coating provides an effective solution for the protection of metal products. By understanding the principle and production method of high zinc layer, we can make better use of this technology, extend the service life of metal products, reduce maintenance costs, and promote the sustainable development of engineering construction.
