| High Velocity Oxy-Fuel Coating (HVOF) |
 |
| |
| Oxygen and a fuel
gas are combusted and through nozzle design and torch design are
accelerated to very high velocities. Popular fuel gases include
Hydrogen, Propylene, Acetylene, and Kerosene. |
| |
| HVOF has become the
quality standard for carbide and cermet materials as gas velocities
over 6,000 feet per second allow particle velocities over 3,000 feet
per second. The result is coating approaching theoretical density
with bond strengths above 10,000 PSI. |
| |
| Since gas
temperature are on the order of only 6,000 degrees Fahrenheit this
is not an appropriate way to apply ceramic materials. |
| |
| PTI has done
considerable research and development with HVOF equipment and
supplies something over forty coatings with these devices. |
| |
| The level of quality
PTI supplies with these devices is among the top two or three in the
industry. In the case of each of these coating techniques PTI sells
coating used in the ´as coated´ condition to mirror like surface
finishes depending on application requirements. |
