Uncommon Substrates Spraying
Kermetico Makes Specialized HVAF Systems to Spray Metal Coatings and Alloyed Powder Compositions onto Uncommon Substrates such as Acme Threads, Thin Walls and Temperature Sensitive Materials.
The Kermetico HVAF process is extremely stable due to the utilization of micro-flame combustion technology enhanced with the catalytic insert.
Modular hardware design makes it possible to build specialized equipment: we adjust combustion chambers, nozzles and powder injectors to achieve optimized results.
A variety of fuel gases and the possibility of multiple additional gas injections make the process even more versatile and efficient.
Kermetico have engineered several systems optimized to spray particular powders. Here is the range of the Specialized guns’ possibilities.
| Feature | S.I. Units | U.S. Units |
| Feedstock | Powders up to 150 microns | |
| Combustion Temperature | 1,500 - 2,000oC | 2,732 - 3,632oF |
| Gun Equivalent Power | 20 - 200 kW | |
| Particle Temperature in the Jet | 900 - 1,600oC | 1,650 - 2900oF |
| Particle Velocity | 400 - 1,000+ m/sec | 1,300 - 3300+ ft./sec |
Why Does this Matter?
Once set up, the spray gun is technologically stable. That means that it will spray coatings with the required quality, spray rate and deposit efficiency with a broad range of spray parameters.
Why is That?
The gun designs are well-calculated and made of modern materials, so our spare parts experience extremely low wear. Depending on the erosive properties of the feedstock material we often get over one hundred hours of spraying from a nozzle.
