1. Characteristics of HVOF thermal spray equipement
The principle of HVOF spray equipment is as fllowing:
The mixture gas of oxygen and fuel gas are sent to the burning area of spray gun exit under high pressure. Then the burning gas is accelerated to form a supersonic flame with the help of compressed air. The spray powder is sent into burning flame and make a functional coating.
2. Configuration of HVOF thermal spray equipment
It consists of spray gun, powder feeder, control system, water chiller and pipeline system. It’s a compact equipment with the feature of easy-operation, stable working performance, low fuel consumption and high-quality coating.
♦ Water chiller
3. Coating material
HVOF spray equipment can spray many kinds of metal powder,such as tungsten carbide(WC-Co) and other hard metal, Cr3C2-NiCr, MCrAlY, Cr C, Cr Co, Cr, etc.
(1) Wear resistant coating
(2) Anti corrosion coating
(3) Thermal Barrier coating
(4) Other functional coating
(5) Renovate the products (Repair the worn-out parts )
(6) Prolong product use life
(7) Rebuild the workpiece
5. Parameters of HVOF spray equipment

Spray gun outside measurement
Spray gun weight
The powder feeder 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 to spray gun. You can regulate the feeding velocity by the localizer on the regulating control panel.
