Like chrome, nickel is one of the transition metals. It is often used for corrosion protection because of its goods resistance to air and water. It is also often used as a diffusion barrier, for example in a chrome plating process. It is used in many applications in the automotive and mechanical engineering industries because of its high-gloss and corrosion-resistant properties.
Nickel surfaces have a long tradition at Rieger Metallveredlung. We have already successfully introduced two patents to the market. Both focused on the nickel plating of aluminum. With us you therefore have a specialist in aluminum electroplating in the area of nickel plating and the associated upstream processes – such as copper plating – and the downstream processes – such as chrome plating.
Nickel is mainly deposited from sulphuric acid electrolytes (so-called Watt's bath).
The structure of the deposited layers can be changed by adding mostly organic substances. Thus, it is possible to deposit not only matt layers (not to be confused with satin or velour effect layers) but also glossy and semi-glossy layers. While the decorative effect is required for the glossy nickel layers, the semi-glossy nickel layers require better corrosion behavior.
