HVOF Coatings

Electro-Coatings provides High Velocity Oxy-Fuel (HVOF) coating services. HVOF is a high-velocity combustive spray that delivers exceptional resistance to wear and corrosion.

Features and benefits:

  • High-velocity spray brings better adhesion to substrates
  • High temperature delivers extremely low coating porosity for better corrosion resistance
  • Combustion-based system delivers better hardness coefficient for improved wear resistance
  • Combined pressure and heat result in smoother coating finish
  • Ceramic or metallic coatings maybe applied to 12mm (1/2") thick

Like many Electro-Coatings products, HVOF provides multiple benefits. HVOF is an excellent choice for those needing high resistance to both wear and corrosion.

HVOF for corrosion and wear resistance

HVOF is applied via a spray head that mixes oxygen and a combustible fuel (a mix of kerosene, acetylene, propylene and hydrogen) to deliver a powdered friction-reducing coating material. The resulting mixture is sprayed in a jetlike effect at extreme temperatures between 5000-6000°F at velocities of more than 7000 feet per second.

The extreme heat and spray pressure of HVOF combine to produce a coating of exceptional hardness, outstanding adhesion to the substrate material, and substantial resistance to corrosion. HVOF generally exceeds bond strengths of 12,000 psi between the coating and substrate, which allows HVOF coatings to maintain nearly 100% of their wear and corrosion resistance in high-temperature environments.

This high level of bond strength also makes HVOF coatings useful for component repair. HVOF coatings may be applied in thicknesses of up to 1/2" without compromising their strength, making it possible to restore worn component surfaces with no additional machining required.
