Hvof Thermal Spray
High velocity oxygen fuel hvof coating is a thermal spray coating process used to improve or restore a component s surface properties or dimensions thus extending equipment life by significantly increasing erosion and wear resistance and corrosion protection.
Hvof thermal spray. These carbide coatings are especially useful in high wear situations. A mixture of fuel and oxygen are combusted within a thermal spray gun producing temperatures near 6000 f 3300 c. There are a number of hvof guns which use different methods to achieve high velocity spraying. Fuel and oxygen mix and atomize within the combustion area under conditions that monitor the correct combustion mode and pressure.
These metal powders are most typically in the carbide family. The hvof high velocity oxygen fuel thermal spray process is basically the same as the combustion powder spray process lvof except that this process has been developed to produce extremely high spray velocity. Which are known for their superior hardness capabilities. Hvof uses a specialized spray gun and carrier gases to spray metal powder onto various substrate materials.
