When it comes to protecting metal parts from corrosion and wear, zinc nickel plating is one of the most reliable surface finishing methods. The idea behind it is simple – zinc nickel plating combines the protective qualities of zinc with the strength and durability of nickel to create a coating that helps metal parts last much longer
What Is Zinc Nickel Plating?
Zinc nickel plating is an electroplating process where a thin layer of zinc and nickel alloy is added onto the surface of a metal object. The coating usually contains around 10-15% nickel, with the rest being zinc.
The process uses an electric current to transfer the metal coating onto the component being treated and once plated, the surface becomes much more resistant to moisture, salt and chemicals. Zinc gives you sacrificial protection, while nickel improves the hardness and durability of the coating and together, they create a strong and long-lasting protective layer.
Why Is It So Popular?
One of the biggest reasons zinc nickel plating, such as at https://www.poeton.co.uk/surface-treatments/plating/zinc-nickel-plating/ is widely used in industries is because it has impressive corrosion resistance. Components coated with zinc nickel can survive exposure to extreme weather conditions, road salt, and also industrial chemicals much better than many other plated finishes.
This makes it especially useful for car parts such as brake components, fuel systems, nuts, bolts, and fasteners.
Another reason for its popularity is that zinc nickel plating can withstand high temperatures better than standard zinc coatings, which makes it suitable for the more demanding engineering applications where heat resistance is important.
