The Ni incorporation rates amount to approximately 10-15%. DIN EN ISO is used if the Standard has also been adopted as a European Standard. Zinc-nickel platings are normally used if the traditional zinc-plating process is insufficient, due to high temperatures or aggressive environmental conditions. 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 Plating: process and advantages The electrolytic plating process zinc-nickel stands out with very good corrosion protection and a high thermal resistance.
