The electroplating process involves applying a metallic nickel coating to the surface of a component by passing an electric current through an electroplating bath. Components made of steel, cast iron, copper or brass are placed as cathodes in the bath, where, under appropriate current and temperature parameters, nickel ions are reduced to form a durable, uniform layer. Depending on the composition of the bath and the process settings, different coating finishes can be obtained – glossy, semi-glossy or matt, allowing for adaptation to aesthetic and functional requirements.
Nickel forms a layer on the surface with high hardness and excellent corrosion resistance, particularly effective in acidic and aggressive environments. As a result, nickel plating is often used in multi-layer protective coating systems, where nickel is a key reinforcing and protective element. The result is not only increased surface strength, but also improved mechanical and aesthetic properties of the details, which remain malleable and give an attractive, shiny appearance.
The process involves thorough surface preparation, including degreasing and cleaning, which guarantees the best coating adhesion. The electrolytic method used in ATOTECH technology is a precise and repeatable process, which ensures high coating quality even with thin layers, extending the service life and improving the functionality of products. The available application methods include both manual rack nickel plating and PUB barrel plating, which allows for the effective treatment of parts of various sizes and shapes.
In short, electrolytic nickel plating is a key galvanic process combining durability, protection and aesthetics of metal surfaces, adapted to a wide range of industrial applications.
