supersonic flame sprayingIn many industries, wear- and corrosion-resistant surfaces are needed to protect critical components. The hypersonic flame (HVOF) spray process can produce very dense hard coatings with fine microstructures to achieve the required protective functions.
The main advantages of this process:
The processed coating is very clean, hard, dense, fine and even
The coating is tightly bonded to the substrate
Liquid fuels have lower coating stress, gaseous fuels allow for thicker coatings
typical application:
Gate valves and valve seats for the oil and gas industry
Turbine parts
paper roller
aircraft landing gear
Process Description
Hypersonic flame (HVOF) spraying uses oxygen and fuel to form a flammable mixture. Liquid fuel HVOF (HVOF-LF) typically uses liquid kerosene as fuel. Gas fuel HVOF (HVOF-GF) uses gas such as propylene, propane, hydrogen or natural gas (methane). The fuel is mixed with oxygen in the gun and the mixture is burned and ejected through the nozzle at supersonic speeds. Nitrogen is usually used as the carrier gas to feed the raw materials into the spray gun in powder form. When the powder exits the spray gun, the ignited gas surrounds and evenly heats the powder material and pushes it to the surface of the workpiece
