Thanks to Tekniker’s outstanding level of specialisation in terms of surface engineering, tribology and coatings, the organisation has become an expert at developing specific solutions for different applications covering a wide range of functionalities on different materials (metallic, polymeric, ceramic). 

Plasma electrolytic oxidation (PEO) is an electrochemical oxidation process that produces a layer of oxide on the surface of an alloy that has been treated thanks to the micro-discharges that occur on the surface when specimens are polarised. 

The PEO technology is extensively used on materials such as aluminium, titanium, magnesium and their alloys, although coatings of this kind are currently being applied to other metal alloys such as, for instance, zirconia or tantalum and even steel. 

When applied to materials, the most outstanding properties delivered by PEO coatings are, among others, high resistance to wear, corrosion and tribocorrosion, thermal and dielectric resistance, improved aesthetic properties and biocidal capabilities.

Thanks to this versatility and with an extensive range of properties, PEO coatings can be used for numerous applications. This technology can be applied to a very broad and diverse range of industrial sectors such as automotive, aeronautics, biomedicine, electronics, etc.

This video explains what this technology is all about, the properties obtained by generating coatings and describes the sectors in which it is currently being applied.
