Gas Fuel Technology with high acceptance in the turbine industry.
Depending on user requirements, propylene, propane, hydrogen or
natural gas may be used as the fuel in gas-fueled HVOF thermal spray
systems. As a result of the high kinetic energy transferred to the particles
through both HVOF processes, the coating material generally does not
need to be fully melted. Instead, the powder particles are in a molten
state and flatten plastically as they impact the workpiece surface. The
resulting coatings have very predictable chemistries that are
homogeneous and have a fine granular structure.
