High-Velocity Oxygen Fuel (HVOF) coating is a thermal spray coating process used to improve or restore a component’s surface properties or dimensions. So continuous machine life by significantly improving erosion and wear resistance, and corrosion protection. Silicon Metallizing¬†the most trustworthy company, in this field presents this Hvof coating. This Hvof coating under the thermal spray coating process to improve the life of industrial equipment.

HVOF thermal spray coating is a continuous one. As seen from the above figure, the combustion takes place in the combustion chamber at a higher pressure of up to 8 bars.The various HVOF systems differ in the type of powder injection, the design of the combustion chamber, and the nozzle geometry. The powder feedstock is usually axially injecting into the hot exhaust gasses from the combustion chamber. Usually, it is depending on the type of HVOF-system and nozzle system.

Advantages Of Hvof Coatings

  • Higher density (lower porosity) due to a higher impact of velocities on the machinery.
  • Higher strength to the substrate band cohesive strength within the coating of the adhesive.
  • Retention of powder chemistry due to less heating of the temperature and the metal.
  • Smoother surface to the equipment due to higher velocity and minimal use of the powder.
  • Better wear resistance for the equipment due to the harder coating on the thermal spray.
  • Top notch hardness due to lesser degradation of the carbide coat.
  • Improved corrosion protection because of the thickness of the cot.
  • Thicker coating due to limitations in residual compounding.
  • Lower oxide content because of lesser flight exposure.
