Coats Bores as Small as 2.5"
Mini-Nova™ and ID-Nova MK-7 torches access internal diameters that legacy systems simply cannot reach. No compromises. No workarounds.
HVOF · Internal Diameter Coatings
Purpose-built HVOF technology for bores, cylinders, and internal surfaces that legacy systems can't reach. ESG-compliant. Field-proven. Ready to validate on your parts.
The challenge
Thermal spray technologies were never designed for precision inside narrow bores. Legacy HVOF systems can't physically access diameters under 4–5 inches. Plasma spray doesn't deliver the coating density required. And hard chrome, the convenient workaround, is being phased out globally under REACH and OSHA regulations.
Meanwhile, mission-critical components: landing gear cylinders, downhole tools, and hydraulic actuators depend on high-performance internal coatings. This isn't a niche problem. It's a global blind spot.

The technology
Spraywerx engineered the ID-Nova™ platform specifically to solve the internal diameter challenge, not as a workaround, but as a production-grade solution.
Mini-Nova™ and ID-Nova MK-7 torches access internal diameters that legacy systems simply cannot reach. No compromises. No workarounds.
WC-CoCr coatings deliver 500+ hours of corrosion resistance in salt spray testing – compared to 50 hours for chrome. Hardness exceeds 1000 HV300.
Hexavalent chromium is being phased out globally. Spraywerx coatings are the validated, compliant alternative — already deployed in aerospace, energy, and industrial applications.

“Spraywerx's technology has fundamentally transformed our coating capabilities. Where we were once constrained to larger diameters, we can now apply high-performance HVOF coatings with precision to small inside diameters as small as 2.5 inches. This breakthrough has enabled us to deliver advanced solutions across industries with demanding wear and corrosion requirements.”— Curt Kadau, President, Extreme Coatings
