What Keronite does

Keronite is a UK-based materials science company and the world's only dedicated provider of Plasma Electrolytic Oxidation (PEO) surface treatment technology for light alloys (aluminium, magnesium and titanium). The technology is an electrochemical process that forms ceramic oxide conversion layers from the substrate itself, delivering corrosion protection exceeding 2,000 hours in ASTM B117 salt spray testing, hardness up to 2,000HV, thermal performance from 0.8–10 W/m·K through 900°C barriers, and dielectric breakdown up to 20kV. Customers include NASA (JWST NIRSpec), Boeing (737NG landing gear MRO), ESA and JAXA (BepiColombo), and enterprises across aerospace, automotive, semiconductor, oil and gas, medical and defense.

The company monetises PEO through three routes: (1) direct contract manufacturing at ISO9001, AS9100 and Nadcap-accredited facilities in Haverhill, UK and Greenwood, Indiana, USA; (2) technology licensing and equipment leasing with consumable electrolyte supply; and (3) factory-gate deployment of dedicated coating lines adjacent to customer factories. Pricing is quote-based and tied to component complexity, with a five-stage New Product Introduction process (Engagement, Solution Development, Industrialisation, Production, Continuous Improvement) underpinning bespoke solutions. Approximately 120,000 customer parts are coated per year across roughly 45 employees, with 2022 revenue of approximately $9 million (or ~£7M) and 50%+ growth that year.

Keronite was founded in 2000, majority-owned by Azini Capital Partners from 2007, and acquired by Curtiss-Wright Corporation (NYSE: CW) for $35 million in cash in November 2022. It now operates as a wholly-owned subsidiary within Curtiss-Wright Surface Technologies' Engineered Coatings Business Unit, maintaining Keronite International Ltd. in the UK and Keronite Inc. in the US.

Core offering

Keronite develops and applies Plasma Electrolytic Oxidation (PEO) ceramic coatings to light alloy components (aluminium, magnesium, titanium) supplied by enterprise customers. The proprietary electrochemical process produces ceramic oxide conversion coatings from the substrate itself, delivering corrosion protection, wear resistance, thermal management, and electrical insulation properties. Services are delivered through three routes: direct coating at ISO9001/AS9100/Nadcap-accredited facilities, technology licensing with equipment leasing, and factory-gate deployment alongside customer operations.

Product overview

Keronite is a materials science company and the world leader in Plasma Electrolytic Oxidation (PEO) surface coating technology. Their core offering centers on PEO coatings applied to light alloys (aluminium, magnesium, titanium) to enhance performance characteristics including corrosion protection, wear resistance, thermal management, and electrical insulation. The company operates a five-stage New Product Introduction (NPI) process: Engagement, Solution Development, Industrialization, Production, and Continuous Improvement. Their product portfolio includes the core PEO coating technology with various specialized variants (corrosion-resistant, wear-resistant, thermal management, electrical insulation), bespoke coating solutions tailored to customer applications, technology licensing and deployment services, and specific applications like Boeing 737NG landing gear repair (BAC5696), antiviral coatings, and aluminum brake rotor coatings developed through the RELIABLE project with InnovateUK and Alcon.

Broad incumbents

• Curtiss-Wright Surface Technologies: Parent division of Keronite since November 2022. Curtiss-Wright Surface Technologies provides a broad portfolio of engineered coatings and surface treatments for aerospace and defense, making it the most direct organizational peer — but it spans many coating chemistries beyond PEO.
• Bodycote: Global leader in heat treatment and surface treatments including anodizing, chromate conversion, and shot peening. Competes with Keronite for outsourced metal finishing work in aerospace and automotive, though PEO is not in Bodycote's portfolio.
• Aalberts Surface Technologies: Provides industrial surface treatments and metal finishing services across aerospace, automotive, and general industrial end-markets. Overlaps with Keronite's aerospace MRO and OEM coating services at scale.
• Oerlikon Balzers: Global PVD/CVD coating specialist serving automotive, aerospace, and tooling markets with wear-resistant and low-friction thin-film coatings. Competes for similar component-performance applications as PEO, though through different chemistry.

Direct peers

• Valence Surface Technologies: Largest independent aerospace surface treatment company in North America, providing anodizing, plating, painting, and non-destructive testing. Direct competitor for outsourced aerospace coatings business, especially after Keronite's Nadcap accreditation.
• Pioneer Metal Finishing: North American provider of anodizing, chromate conversion, passivation, and specialty coatings for aerospace, defense, and industrial customers. Direct competitor in the outsourced metal coating services category Keronite operates in.
• Anoplate Corporation: US-based metal finishing specialist offering anodizing (including hardcoat), chromate conversion, and a range of surface treatments serving aerospace, medical, and electronics customers. Closest direct comparator in anodizing-adjacent coatings.

Regional players

• Hohman Plating & Manufacturing: US-based metal finishing and coating services company offering anodizing, plating, and surface treatments primarily serving aerospace and defense customers. Geographic peer for Keronite's Greenwood, Indiana facility.
• MPC Plating: UK-based metal finishing and surface treatment provider serving aerospace and industrial customers. Geographic peer for Keronite's UK operations in Haverhill, competing for similar OEM/MRO coating work.

Emerging players

• Keronite competitor (e.g., Magoxid-Coat providers): AHC Oberflächentechnik (atec-group) and similar European players offer plasma electrolytic oxidation / micro-arc oxidation for magnesium and aluminum components. Closest direct technology peer in the PEO/MAGOXID space, though smaller scale than Keronite.
