The HVOF (High Velocity Oxy-Fuel) spray process is a more recent advancement in thermal spray methods for coating machine parts. Unlike traditional flame spray, HVOF utilizes a high-speed jet to launch the coating material. The super-sonic jet means that the particles hit the surface with much greater force, leading to better coating results.
This technique uses gases like propane, propylene, acetylene, hydrogen, or even liquid fuels like kerosene, to create the powerful spray. This innovation has improved the way we apply coatings to machine parts, resulting in enhanced performance.
