Zinc plating
Inexpensive zinc plating (chromate treatment) that can provide corrosion resistance.
Zinc plating is an indispensable presence when it comes to plating. The zinc coating is a bluish-silver metal that has a glossy appearance and exhibits paramagnetism, and the choice of zinc plating suitable for the material can affect its corrosion resistance. Zinc plating can be achieved through two methods: one is to deposit zinc metal using electric power, and the other is to immerse the material in molten zinc, both of which provide a plating treatment that imparts high corrosion resistance. Zinc plating has a high rust prevention effect and is mainly applied to iron products, as an inert film is formed on the zinc plating. Since zinc has a greater tendency to ionize than iron, even if there are pinholes in the plating film, zinc acts sacrificially to prevent rust on the base material, achieving a high level of corrosion protection. This is known as sacrificial protection.
