Description :

Hvof Process(High Velocity Oxy Fuel Spray System):

HVOF system used to develop wear resistant coatings for Aero engine, Power, Paper, Oil & refinery Sectors.

Process description:

In High Velocity Oxy Fuel (HVOF) Spray System, Continuous combustion of the oxygen and fuel gas occurs in the combustion chamber and the resulting hot, high pressure gas is allowed to expand and accelerate through orifices into the nozzle. A carefully measured flow of powder is introduced axially into the nozzle, allowing sufficient heating and acceleration of the powder particles. The powder is heated and accelerated by the products of the combustion, usually to temperatures above its melting point and to velocities approaching supersonic velocities.
