High Velocity Oxygen Fuel (HVOF) 

The High Velocity Oxygen Fuel (HVOF) process produces durable metal, carbide, and a multitude of specialty coatings. A complete line of powders is available, which are specifically engineered for application with the HVOF system. This technology can be utilized in a range of applications leveraging the ultra-dense HVOF coating properties and the resulting wear-resistance.

Following you'll find Equipment, Parts & Information

for the Thermach HVOF Thermal Spray Coating System.

To automate your thermal spray operation, see the NEW AT-3200 Mass Flow Control Console here.

WHERE HVOF EXCELS

HVOF combustion spraying deposits coatings with higher density, lower oxide content and better bond strength than similar coatings applied with flame, wire-arc, or plasma spray processes. These characteristics make HVOF the process of choice for applying carbide coatings for: aerospace applications, rotating shafts in pumps and compressors, valves, seals, paper/pulp rollers and corrosion/wear resistance.

 

HVOF coatings are typically denser and adhere better than plasma sprayed coatings. Wear resistant coatings such as WC/Co typically display bond strengths exceeding 83 MPa (12,000 lb/in.2), “as sprayed” densities greater than 99% and microhardness of 1,000 to 1250 Hv300.

  • Why Thermach?
    Thermach is a specialist. We manufacture equipment and parts for the thermal spray industry. That means we are your coating partner, not your competitor.
  • Thermach delivers less maintenance costs...
    ...when compared to conventional pull or push-pull systems. You'll see the difference.
  • Our lightweight torch is only 2.3 lbs and has no moving parts...
    With the drive mechanism on the wire feeder, our torch stays light, and reduces operator fatigue.
  • Only Thermach gives you patented Quick Change Wire Guides!
    Compared to conventional wire guides that are threaded into the torch, our Quick Change wire guides allow you to change worn out guides in less than 30 seconds, with zero tools. For added life, simply rotate the guides 180° before typical replacement.
  • This is a modular system designed to fit any workspace...
    Stack the wire feeder on top of the power supply or separate them up to 50 feet at 100% duty cycle.
  • Our complete system weighs approximately 300 lbs!
    Weighing in at less than the typical electric arc spray system, your team will appreciate the flexibility and the AT-400’s ease of handling.
