HVOF Gun (High Velocity Oxygen Fuel Gun) instruments are a subdivision of the flame spray gun. There live two distinctions in middle of HVOF as well as ordinary flame spray. through warm & activated powdered coating material, HVOF Gun employs a narrow discharge & a broad nozzle. HVOF Gun devices are characterized by employing hypersonic gas velocities, which are larger relative to MACH 5. The most significant velocities afford kinetic energy which enables the provision of coatings that are too thick & extremely well attached to the as-sprayed status. HVOF Coating process with an HVOF Gun needed an extremely high velocity. Before affecting the substrate, this high velocity is utilized to drive the particles to supersonic speeds. High explosion pressure & great gas also particle velocity result in lofty coating grade in HVOF coating process. There are two kinds of HVOF guns driven by fuel type like gaseous or liquid in nature.

HVOF Spray Gun

The HVOF (High Velocity Oxygen Fuel spray gun) Thermal Spray gun process is equal to flame powder spray gun, accompanied by exception that it existed designed to carry exceptionally lofty spray acceleration. There is a variety of HVOF guns available, each with its own method of gaining lofty speed spraying. A high-pressure water-cooled HVOF flame chamber with a long nozzle is one way. Fuel (kerosene, acetylene, propylene, also hydrogen) also oxygen live equipped into square, where discharge delivers a burning, high-pressure flame that is propelled from top to bottom a nozzle at a lofty acceleration. Powder is basically provided at lofty pressure from nozzle's center.

HVOF Coating Process

After a thorough review of the literature, two types of HVOF coating process powders, (1) WC-12CO and (2) Cr3C2NiCr, were chosen for the discharge Spray Coating Process also the High Velocity Oxygen Fuel Spray Coating Process. HVOF Gun is engaged for the coating process to prevent the surface of the material from rusting after surface preparation with the usefulness of an abrasive blasting machine. The indicated coatings contain good bond strength also wear resistance, according to research publications. 

Tungsten Carbide Cobalt  (WC-12CO): Tungsten Carbide Cobalt powder creates exceptionally dense also homogenous coatings with excellent abrasive wear resistance when sprayed using the Detonation Spray technique. Ambica Enterprises provides Tungsten Carbide powder, ceramic powder, and molybdenum powder, The powder is sintered & agglomerated, with a particle size of -45+20 microns.

Chromium Carbide-Nickel Chromium Powder (Cr3C2NiCr): When sprayed utilizing the Detonation Spray technique, Chromium Carbide  & Nickel Chromium powder generate coatings that are extremely hard, dense, also well-bonded. For resistance to feeling uneasy wear also abrasive particle oxidation, a Chromium Carbide & Nickel Chromium coating is advised. The powder is sintered & agglomerated, with particle sizes ranging from 10-45 µm.

Benefits of HVOF Gun 

  • Low porosity (<1%)       
  • Higher bond strength (>10000 psi)
  • Uniform repeatability
  • Low operating cost
  • Higher particle velocities
  • Stable deposition rate
  • Controlled coating thickness
  • Safety interlocks

HVOF Tungsten Carbide Coating

HVOF Tungsten Carbide coatings are deposited by thermal spray. During this process, fuel gas & oxygen are pre-mixed, & provided at high-pressure into a discharge enclosure, where they burn to have a burning, high-pressure gas stream. Tungsten carbide powder bits are infiltrated directly into this combustion area of gun underneath automatic control. As high-velocity gas stream (containing semi-molten powder ) is supervised toward substrate, impact also deposition of the particles on surface assembles a wide, uniform coating, typically with< 1% porosity, an oxide content of < 1%, & a bond strength in excess of 80 MPa (10 ksi). HVOF coating process is maintained release in a spray booth, with a robotic apparatus.
