Thermal Spraying technology
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
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
- Spray powders for HVOF spraying
- Self fluxing alloys
- Ceramic spray powders
Application:
- Premium coating system for aircraft turbines
- Components for textile machines, pulp- and paper machines and printing machines
- Hydraulic engineering
