During hvof tungsten carbide thermal spraying coating
Hvof thermal spray coating powder
Completed hvof thermal spray systme
Characteristics of hvof thermal spray system
The principal of HVOF thermal spray system is: the mixture gas of oxygen and fuel gas is sent to the burning area of hvof spray gun exit under high pressure. Then the burning gas is accelerated to form a supersonic flame with the help of peripheral compressed air. The hovf spray powder is sent into burning flame and make a functional coating.
Hvof equipment consists of hvof spray gun, hvof powder feeding machine, hvof control system, heat-exchanger system for hvof and pipeline system for hvof. hvof it’s a compact equipment with the traits of easy-operating, stable working performance, low fuel consumption and high-quality coating.
Configuration of hvof thermal spray systme
It consist of hvof control cabinet, hvof spray gun, hvof powder feeding machine, water chiller and cables for hvof
hvof thermal spray system spray materials
HVOF thermal spray system can spray metarial of part of Alloy powder ( Tungsten carbide /WC-Co, Cr3C2-NiCr, MCrAlY, Cr C, Cr Co, Cr, etc.)
Advantages of process hvof thermal spraying coatings
1. Wear resistant
2. Anti Corrosion
3. Thermal Barrier coating
4. Recycle the products (Repair the worn-out parts )
5. Prolong product use life
6. Rebuilding of under size parts
7. The coating has low porosity and high bond strength and hardness

The hvof powder feeding machine is used to store spray powder and send them to burning flames according to technological requirements. The feeding gas is nitrogen, which pulverizes the powder and sends the pulverized particles along with the gas to spray gun. You can regulate the feeding velocity by the localizer on the regulating control panel.
