HVOF Equipment for Sale: Convertible Thermal Spray Coating Systems

Kermetico Convertible equipment offers the best solution for the HVAF vs. HVOF discussion. You no longer need to choose between standardized HVOF equipment and our efficient HVAF processes. 

You can use our Convertible HVAF & HVOF equipment spraying coatings in HVOF mode conforming to legacy HVOF standards or in an HVAF mode depositing higher-quality and less expensive coatings.
Our gas fuel HVOF allows spraying corrosion and wear resistant coatings with the best quality and cost.

A Description of Our Gas-Fuel HVOF Equipment and Thermal Spray Coating Process

Kermetico Gas-fuel High-Velocity Oxygen Fuel HVOF equipment utilizes continuous combustion of gas fuel, oxygen and air to generate a high velocity gas stream propelling a powder feedstock towards the surface to be coated.

The powder partially melts in the stream and deposits on the substrate. Kermetico C equipment works in HVOF mode at a particle temperature up to 1,700°C (3,100°F) and accelerates the particles sized at -45/+15 microns to 700-850 m/s (2,300-2,800 ft./sec.).

The HVAF Coating Mode

Working in High Velocity Air-Fuel mode, our Convertible equipment deposits coatings using continuous combustion of gaseous fuel and air, propelling metal, or carbide powders towards the substrate.

The feedstock is being heated below its melting point, and it is much less oxidized or decomposed compared to coatings made with conventional HVOF equipment.

Those features allow us to spray fine particles (5-20, 15-30 microns) accelerated to over 1,000 m/s (3,280 ft./sec.)

Smaller particles are difficult to spray with conventional HVOF equipment due to the high oxidation rate and partial evaporation in the elevated temperature environment.
