Keronite PEO Coating


The Advantages of Keronite Coating

Keronite produces hard, dense ceramic coatings for light alloys that can be custom-formulated to provide a combination of different characteristics. Plasma Electrolytic Oxidation (PEO) is an advanced surface treatment technology that extends the life of magnesium, aluminum, and titanium components through a range of key characteristics unique to PEO. Our coatings are far superior to competing coatings, such as anodizing and thermal sprays.

These improved performance characteristics facilitate component weight reduction and the broader use of light alloys in multiple industries. Our coating solutions significantly improve these metals’ corrosion resistance, wear resistance, and overall durability, extending their lifecycle and performance in demanding environments.
