Plasma ceramic, developed by ELB, represents the future of surface technology, also known as nanoceramics or PEO (Plasma Electrolytic Oxidation) technology. This innovative process creates a micro-crosslinked, atomically bonded, and nanostructured surface, among the world's hardest materials, capable of withstanding high stress.
With atomical bonding, this layer withstands loads up to 1,000 times higher than conventional anodized aluminum, maintaining the light metal's volume and weight. Parameters of CERANOD® plasma ceramics can be tailored to any application, offering precise physical, mechanical, and functional properties.
Compared to hard anodizing, CERANOD® enhances corrosion and heat resistance, as well as abrasion resistance. Light metals with a sealed CERANOD® surface endure over 2,000 hours in salt spray tests without significant corrosion, while unsealed layers last over 500 hours on certain alloys.
CERANOD® coating exhibits exceptional heat resistance, enduring temperatures up to 2,000 °C briefly without alteration. Magnesium PEO reaches up to 1,100 HV hardness, while aluminum PEO achieves up to 2,400 HV.
The nanoceramic structure allows for further treatments such as cold or hot sealing with PTFE, adhesive joints, or industrial coatings like powder coating or electro-dip coatings.
CERANOD® plasma ceramic surfaces demonstrate significantly higher wear resistance than hard anodized surfaces, applicable to a wider array of alloys. Depending on the base material, surface hardness can triple that of hard anodized surfaces with low roughness values. This technology also offers exceptional corrosion protection, enabling the use of light metals like magnesium previously deemed unsuitable due to corrosion concerns.
