Keronite

Keronite International Ltd. specializes in advanced surface treatments for light alloys, primarily using its proprietary Plasma Electrolytic Oxidation (PEO) technology. This electrochemical process transforms the surface of aluminum, magnesium, and titanium into a hard, dense ceramic layer, significantly enhancing durability, wear resistance, and corrosion protection. The resulting coatings allow lightweight metals to exhibit the performance characteristics of heavier materials like steel, facilitating weight reduction in components across various industries.

Founded in 2000, Keronite began with a mission to advance materials science through PEO. The company has since expanded globally, establishing a US subsidiary in 2004 to serve the aerospace and automotive sectors and opening the first purpose-built PEO facility in Greenwood, Indiana, in 2007. A key milestone occurred in November 2022, when Keronite was acquired by Curtiss-Wright Corporation for $35 million and integrated into its Aerospace & Industrial segment. This acquisition aimed to broaden Curtiss-Wright's surface treatment portfolio and leverage its global sales channels for further growth.

The company's business model revolves around providing bespoke coating solutions tailored to specific client applications. It serves a diverse client base in demanding markets, including aerospace, defense, automotive, industrial vehicles, and semiconductor manufacturing. Revenue is generated by deploying these custom coatings on customer parts, processing over 120,000 components annually. The PEO process is noted for being more environmentally friendly than traditional methods like hard anodizing, as it uses low-concentration alkaline electrolytes free of heavy metals.
