High-Velocity Oxygen Fuel (HVOF)  is a thermal spray  process which is widely used in tungsten carbide coating to extend magnetic separators'life and increase erosion and wear resistance

Carbide particles are spayed on the surface of the magnetic separator by means of high temperature and high velocity gas stream to produce a dense coating for corrosion protection and improvement of hardness

Advantages:

1.Operation in very high temperature is allowed

2.Good performance in hardness ,erosion and wear resistance

3.Cost saving

4.Best operation choice for abrasive materials

5.Extend equipment's  life
