Electrolytic nickel plating

In electrolytic nickel plating, the nickel coating is applied by electrolysis. To ensure effective corrosion protection, the base material must be completely sealed by the nickel layer and therefore 100% pore tight. This requires a minimum layer thickness starting at approx. 20 µm, depending on the substrate.

We can deposit the nickel coating in a matt, semi-bright or bright finish. For a perfect visual result, we first have to grind, brush or polish the product. This is because any imperfection in the base material is accentuated, especially with a bright nickel coating. After nickel plating, you can choose to chrome plate the product.

For better corrosion resistance, a layer of duplex nickel coating can be applied. We do this for high-grade products used in harsh (or corrosive) conditions and, for example, when restoring car, motorbike or yacht components. For this duplex nickel plating, we deposit a semi-bright nickel undercoat first and then a bright topcoat. The extra protection is due to good pore density and the difference in standard potential between the layers.
