HVOF spray equipment can get the advanced level of similar foreign products, superior performance, ease of operation. Control cabinet adopts touch control terminal to put operation/ setting/display/ process and fault alarm monitoring together, simplifying panel design, easy to use, simple operation and intuitive.

 

(2)Powder feeder for HVOF spray machine(HVOF coating machine)

 

Powder feeder for HVOF spray machine(HVOF coating machine) is a device that used to store spray powder according to process requirements to deliver powder to the gun  . Nitrogen is the powder feeding gas. Spraying powder through a gas atomization vibration so that the powder feeding device to exit, along with to send powder gas left to send powder barrels into the spray gun.The powder feeding speed can be adjusted  by adjusting potentiometer on control panel.

 

(3)Spraying gun for  HVOF spray machine(HVOF coating machine)

 SPRAY GUN FOR SX8000 SPRAY GUN FOR SX5000

 

Spray gun uses kerosene as fuel, oxygen as the combustion gases, air and water for the cooling body, nitrogen for feed powder. This gun can be working with a long continuous stability.

 2.principle of  tungsten carbide powder HVOF coating machine

    the combustion supporting agen oxygen atomizes the kerosene fully with atomizing nozzle, then they will enter into combustion chamber as flammable mixed gas.It will burn in high temperature and high pressure after the ignition system ignites it. high-temperature and high-pressure supersonic flame flow will be formed after it’s burning in the Laval nozzle. powder feeding system will send the powder material from the area of low pressure into the flame flow, heating accelerated then spray to the workpiece surface to form high quality coatings. 

 

3.characterics of  tungsten carbide powder HVOF coating machine

        HVOF coatings may be as thick as 12 mm (1/2"). It is typically used to deposit  wear resistant and corrosion  resistant coatings on materials, such as ceramic and metallic layers. Common powders include WC-Co, chromium carbide, MCrAlY, and alumina. The process has been most successful for depositing  cermet  materials (WC-Co, etc.) and other corrosion-resistant alloys (stainless steels, nickel-based alloys, aluminium,  hydroxyapatite  for medical implants, etc.).

 

Coating Features:
     High Density
    Optimum Hardness
    Smooth Surface
    High bond Strength
    Excellent wear resistance
    Reduced Oxide content  than plasma coating

 

4.characterics of  tungsten carbide powder HVOF coating machine
