What is Alkaline Zinc Nickel Plating?

Alkaline zinc nickel plating is a method where a zinc and nickel alloy coats a metal surface. It combines the benefits of both zinc and nickel. The end result? A layer that resists rust and provides excellent wear protection.

Why Choose This Process?

Many industries prefer the alkaline zinc nickel plating process for several key reasons:

1. Corrosion Resistance: The alloy creates a strong barrier against moisture and air, preventing rust.
2. Durability: It can withstand harsh conditions and heavy usage.
3. Easy to Maintain: The coated surfaces are easier to clean and maintain.

Steps in the Alkaline Zinc Nickel Plating Process

Curious about how it all happens? Here’s a step-by-step breakdown:

1. Preparation: First, the metal part is cleaned. Any oil, dirt, or old coatings are removed.
2. Rinsing: After cleaning, parts are rinsed in water to ensure all contaminants are gone.
3. Plating Bath: The parts are immersed in a bath containing the zinc-nickel solution.
4. Electroplating: An electric current runs through the bath. This helps the zinc and nickel ions deposit evenly on the metal surface.
5. Post-Treatment: Finally, the coated parts go through a treatment process to improve adhesion and enhance properties.
