High Velocity Oxygen Fuel (HVOF)
Thermal Coating System
Basic Operating
Principal
|
|
An oxygen and fuel
(kerosene)
mix is atomized after it passes through an opening and into the
combustion chamber. It is then ignited creating a small jet stream. A
special combination of alloys in powder form are instantaneously
introduced into the combustion jet stream, melted, atomized and
propelled towards the substrate at incredibly high velocities
(supersonic speeds up to mach 3). The kinetic and thermal energy
imparted to the particles cause the coating to be virtually bonded to
the substrate. |

HVOF is a relatively
new coating method that provides high-density, extremely wear-resistant
coatings. This system is more versatile for metallic and carbide
coatings and provides resistance to wear parameters like erosion,
corrosion, abrasion, sliding, fretting, heat and thermal resistance.

HVOF coatings have proven their worth in the most demanding industries
and most extreme conditions. Pulp & paper, power generation, oil and
gas industries, jet engines, sewage treatment, aerospace engineering,
nuclear facilities, chemical plants, and marine environments are only a
few of the places where HVOF has become an invaluable coating process.
