Thermal Spraying technology


hvof High velocity oxy-fuel spraying (HVOF)

Characteristics:
  • Combustion of flammable gases
  • Acceleration of gases in a nozzle (HVOF = High Velocity Oxygen Fuel)
  • The powder particles are accelerated to very high velocities (up to 800 m/s)
  • Powder partially melts in the flame

Advantages:
  • Dense coatings
  • High quality coatings
  • Excellent coating material connection
  • Reliable process

Application:
  • electrical and thermal insulating coatings
  • Protection against corrosion
  • Protection against wear
plasma Atmospheric plasma spraying

Characteristics:
  • Spraying technology with high thermal energy and high temperature
  • Only spraying material in powder form usable
  • High investment costs and operating expenses

Advantages:
  • High coating quality achievable, especially suitable for highmelting-point materials, primarily ceramics

Material for thermal spraying:
  • Spray wires
  • Spray powders for flame- and plasma spraying
