The process of electroplating applies functional layers of only a few µm on the product base material in order to achieve the designated surface characteristics. The treated parts pass through a variety of process solutions.
The relevant steps during the treatment process are divided in pre-treatment, the actual plating process and the final after-treatment.
Electroplated surfaces come in the form of a stand-alone process or a combination of electroplating with other alloys or surface finishes. A passivation or sealer at the end of the process lead to a higher functional corrosion protection.

Zinc-Nickel – an optimum of corrosion protection
The electroplated surface finish with Zinc-Nickel offers extremely high corrosion resistance with excellent long-term protection against the exposure to high thermal stress. Internal coatings applied through internal anode technology as well as a final passivation are possible. The after-treatment with selected top coats raise the corrosion and media resistance significantly. Surface finishes with zinc-nickel show an extremely high thermal stability. The process of zinc-nickel acid additionally offers excellent optical characteristics.
Applied fields of zinc-nickel surfaces:
- automotive and supplier industry, e.g. engine compartment, landing gear and underbody areas (turned parts for brake and magnetic systems)
- utility vehicles
- construction machinery
- precision engineering
- offshore facilities
- window construction
