Hvof Spray
The study of the hvof spraying process is useful for.
Hvof spray. High velocity oxy fuel coating spraying hvof high velocity air fuel hvaf warm spraying. And improved life of mating components. Enabling components to operate in higher lower temperatures. The detonation gun d gun process was the first type of hvof process used.
In classical developed between 1910 and 1920 but still widely used processes such as flame spraying and wire arc spraying the particle velocities are generally low 150 m s and raw materials must be molten to be deposited. Developing new cost effective coating materials providing low porosity coating with better corrosion resistance indirectly controlling the damage and the risk of catastrophic failure due to corrosion. In hvof processes kinetic energy of particles is more important than temperature. Enabling components to operate within harsh chemical environments.
