Plasma Ceramic

Innovative surface technology


What is plasma ceramics?

Plasma ceramics (PEO Technology) is a unique technology for surface treatment of lightweight alloys. A ceramic surface is extremely resistant to corrosion and wear.

This method greatly improves the durability of components, even treatments are often reduced, so that a cost reduction potential is given.


Is the process environmentally friendly?

The environmentally friendly CERANOD® process does not contain chromium nor other toxic heavy metals.


Does the coating stresses as high?

High stresses holding the flexible and compliant layer was without being exposed to stresses which would allow conventional ceramic failure.


Is plasma ceramics suitable for corrosion protection?

Aluminum with a sealed CERANOD® surface resists more than 2000 hours in salt spray test with no significant signs of corrosion.
Even the unsealed layer holds on some alloys more than 500 hours.


Coatings can be applied?

Due to its microporous structure the surface is a perfect primer for a number of top coatings such as metal coatings, impregnation with PTFE and other lubricants, sealants to increase the corrosion resistance, ply adhesion and a wide range of industrial coatings, such as powder coating or electro-dip lacquer treatments.

Advantages over the hard anodizing

CERANOD® plasma ceramics offers on aluminum up to seven times higher wear resistance than hard-anodized surfaces. Moreover, it can be applied to a wider range of alloys.
Depending on the base material surface provides up to three times higher hardness than hard anodizing.

Advantages over plasma-sprayed ceramic

The dipping process with high scattering power, in contrast to spray processes protect internal surfaces and undercuts on highly complex parts.


Other advantages of the ceramic plasma

Dishwasher test: More stable than sealed anodic coating
Cleanrooms: Proposal has no emission of dust particles
Insulator: Better electrical insulation than conventional polymer insulators
