Zinc nickel plating is a type of surface treatment that is obtained through an electroplating process. It serves a purpose as a protective barrier that helps to prevent erosion and corrosion. Zinc nickel plating is an excellent surface treatment that can be widely applied to a huge variety of components and is used in several different sectors.
What Is Zinc Nickel Plating
Zinc nickel plating involves applying a thin alloy coating to a metal surface, typically steel. This coating usually ranges from 5 to 25 microns in thickness and provides a protective barrier against environmental damage.
One of its key characteristics is that it acts as a sacrificial coating. This means it corrodes in place of the underlying metal, helping to extend the lifespan of the component.

Key Benefits of the Process
A major advantage of zinc nickel plating is that it provides excellent corrosion protection even in the most severe environments. Examples include automotive and marine. Corrosion protection is required where there is exposure to moisture, salt or varying temperatures.
This coating is often specified as an alternative to cadmium plating. The use of cadmium is being phased out by a growing number of original equipment manufacturers concerned with reducing the environmental impact of their products. With comparable performance characteristics, zinc nickel coatings offer a true environmentally friendly alternative.
In addition, zinc nickel plating is considered cost-effective, providing long-lasting protection without frequent replacement of parts.
