Plasma electrolytic oxidation

Plasma electrolytic oxidation – Innovative coating

Plasma Electrolytic Oxidation (PEO) is an innovative method that creates high-quality ceramic coatings on metals. This technology has become a significant tool in various industries due to its versatile properties and excellent results.

What is plasma electrolytic oxidation?

PEO is an electrochemical surface treatment method that promotes the formation of a solid, thick ceramic oxide coating on metals. This method enhances the properties of metal surfaces, increasing their longevity.

Sizes of processed parts and metals used

It is used for lightweight alloys with a high content of aluminium, magnesium, and titanium, as well as other metals such as zirconium, tantalum, niobium, hafnium, and cobalt.

Size of processed parts: up to 0.24 m².

Advantages of PEO coating plasma

Electrolytic oxidation provides high resistance to wear and friction. The PEO coating ensures that the part does not conduct electricity. The coating also improves resistance to scratches and cracking, becoming a crucial choice in many technical applications. Plasma coating ensures very long-lasting colour durability.


Applied in aerospace and automotive industries, tribology, and medical engineering. It is also used in pre-treatment before sealing with sealants, paint, or other polymer applications.
