SURFACES

Chrome


Chrome is used both for decorative and functional coatings, whereby chrome is usually not used as a pure chrome coating, but in a layered system with other metals. Most of these systems are based on copper-nickel or duplex layers (usually nickel, semi-bright and bright nickel). By choosing different layer thicknesses and base materials, different degrees of hardness, corrosion and wear properties can be achieved. The classic chrome coating has a silvery shiny appearance. Depending on the lower layers, different degrees of gloss and matte can be achieved. These surfaces, known as matte chrome for example, are not produced by the chrome, but by the velour nickel coating underneath. 

Alternatively, matte chrome coatings can be created by brushing or micro-polishing. This treatment results in technically high-quality surfaces as well as attractive surfaces with a stainless steel character.

Chrome coatings can have different properties and colors due to different chromium electrolytes. This is achieved through classic chromium-VI processes as well as new chromium-III processes, in which the surface, for example, is provided with a high-quality black optic (WICROM® Black).

Remarks

The chromium plating of surfaces with substances containing chromium-VI has been significantly restricted since 21 September 2017. (See REACH Regulation)

Since this date, hexavalent chromium compounds may only be used by companies that have applied for and received approval for their use in a timely manner, or by downstream users who meet all the conditions set out in the official approval notice. As a downstream user, we meet the application requirements and work exclusively with suppliers and manufacturers who have this approval. 

We also work with attractive alternatives. Chromium-III processes have been included in our range of services since 2015. Together with our long-standing process suppliers and partners, we are working on the further process developments in order to be able to replace chromium-VI processes in the long term.
