Zinc – Nickel Plating (Zn-Ni)
Process and Advantages
Zinc-nickel platings were developed as a result of increasing requirements with regard to corrosion protection, in particular from the automotive industry, against exposure to temperature, road salt and climatic conditions. Zinc-nickel platings are normally used if the traditional zinc-plating process is insufficient, due to high temperatures or aggressive environmental conditions. The Ni incorporation rates amount to approximately 10-15%. The ZnNi surfaces offer optimal cathodic corrosion protection and are highly resistant to thermal loads (up to 120 °C). This type of surface finish is usually used on steel, ferrous cast components and powdered metals. We offer the electrodeposition both as rack plating and as barrel plating.
