Keronite applies plasma electrolytic oxidation (PEO) coatings to improve the performance of light alloys such as aluminum, magnesium, and titanium. PEO creates very hard, uniform, and corrosion-resistant oxide coatings through millions of plasma discharges during electrolysis. Keronite has developed PEO coatings for applications such as wear protection on aircraft parts, thermal barrier coatings for engines, and corrosion protection in oil and gas components.
