Metallic coatings

Coating of aluminum

Aluminum forms on the surface a native oxide layer, which offers a certain protection against corrosion. If the oxide layer is mechanically injured, it forms immediately anew, it is however, resistant to pH values from 4.5 to 8.5. In order to improve the existing protection, it is in many cases necessary to coat the part, for example, for outdoor areas in the case that the components are exposed to the weather.

The focus stays on the protection against wear, corrosion resistance of aluminum coating and pretreatment for a subsequent application of paint and varnish on the aluminum surface.
