HVOF Gun | Thermal Spray Gun | Flame Spray Gun Manufacturer in INDIA

HVOF Gun

HVOF stands for High-Velocity Oxy-Fuel. In this high-velocity oxy-fuel is supplied by the gun.HVOF Gun required a very high velocity for the coating process. This high velocity is used to propel the particles at supersonic speed before impact onto the substrate. In the spray process high combustion pressure and high velocity of gas and particle resulting in high coating quality.
Two types of Hvof on basics fuel

  • Liquid Fuel
  • Gas-Fuel

HVOF Gun Application


  • High density. Typical coatings have less than 2% porosity and some coatings as low as 0.5% porosity. 
  • High bond strength. For example, typical carbide coatings sprayed with HVOF exhibit bond strengths in excess of 69 MPA (10,000 psi). Other coating materials sprayed with HVOF have significantly higher bond strengths than the same materials applied using other atmospheric thermal spray processes such as air plasma spray.  
  • Optimum Hardness. A 12% tungsten carbide / cobalt coating will have a typical microhardness of 1100 to 1350 DPH300.
  • Improved Toughness. Depending on the chemistry and other factors, the short dwell time and lower temperatures of HVOF can produce wear-resistant coatings with excellent impact resistance. 
  • Higher Coating Thickness. Coatings exhibit greater coating thickness limits than plasma, combustion or wire coatings of the same coating material. These high thickness limits are attributed to a stress-relieving ‘shot-peening’ effect produced by the high-velocity particles impacting upon the previous layers of coating. Some tungsten carbide coatings can have a thickness greater than 6.4 mm (0.250 inches). Beneficial Residual Stress. Compressive residual stresses and, in some cases, very low tensile stresses enhance the fatigue life of a coated component, reduce the susceptibility of cracking and permit greater coating thickness limits. 
  • Excellent Wear Resistance. HVOF coatings can exhibit superior resistance to sliding / adhesive wear, fretting, erosion or cavitation depending on the material and process parameters chosen. 
  • Superb Corrosion Resistance. The high density and exceptional metallurgical properties of HVOF coatings provide enhanced resistance to the effects of corrosion, including hot corrosion, oxidation and the effects of corrosive media such as acidic and alkaline atmospheres and liquids. 
  • Fine Surface Finishes. Smooth surfaces finish allow HVOF-produced coatings to be used in the as-sprayed condition for many applications. Coatings can be machined, ground, lapped, honed or super finished to produce very high surface finishes to precise tolerances.
