In a joint initiative by AUTOMOTEAM GmbH, DGO Deutsche Gesellschaft für Galvano- und Oberflächentechnik e.V. and other representatives from industry and research, a standardization application on the subject of "Plasma electrolytic oxidation of aluminium" was submitted to the DIN Non-Ferrous Metals Standards Committee (FNNE) in spring. At its most recent meeting on August 20, the responsible DIN Aluminum Division Council approved this application. The next step is to establish an independent DIN working committee on 2 December 2020 in order to define and specify the content of the standard. For this reason, AUTOMOTEAM GmbH is calling on interested companies to actively participate in this working committee!
Plasma electrolytic oxidation (PEO), also known as MAO (micro arc oxidation), is a surface technology process for anodic conversion coating formation in which the coating is primarily formed by complex thermochemical reactions in a gas-phase solid plasma.
The microporous, microstructured and chemically activated metal-ceramic PEO layers usually achieve a thickness of 10-200 μm and, due to a complex microstructure consisting of amorphous and nano- or microcrystalline phases of different substances, very high heterogeneous microhardnesses (from 100 HV up to 2000 HV) and novel multifunctionality.
The fields of application range from highly wear-resistant and heat-resistant to high-quality decorative, thermally insulating or thermally conductive, electrically insulating or electrically conductive, light-reflecting or light-absorbing coatings on aluminum components, as well as corrosion-protective coatings for magnesium and bioinert and bioactive coatings for medical titanium implants. Another advantage of PEO coatings is their excellent compatibility with other surface technologies such as cathodic dip coating, powder coating, PVD, screen and digital printing, etc.
The current standardization project aims to increase the range of applications of the surface technology that has been available industrially for many years under the name METAKER® Surface, among others, and to harmonize the associated customer-supplier relationships.
If you are a current or prospective developer, user or end user in the field of the PEO process and are interested in actively participating in the DIN working committee "Plasma Electrolytic Oxidation of Aluminum", please contact us by November 13 at the latest:
