1 GENERAL DESCRIPTION:
1.1 INTRODUCTION HVOF Since it’s first application 20 years ago, High Velocity OxygenFuel (HVOF) spraying has gained increasing importance in the thermal spray market. The special feature of this technique, as compared to other TS techniques, is that the coating materials are less heated and impact on the components which are to be coated with remarkably higher velocities. In HVOF systems a flame is created by combustion under high pressure, resulting in gas velocities of more than2000 m/s. The spray powder is injected into this gas stream.
1.2 HVOF K2 SYSTEM The HVOF K2 System is a HVOF System of the third generation. Instead of a fuel gas this system uses a liquid fuel (kerosene). The system operates at combustion chamber pressure typically up to 10 bar. The powder is injected radially into the gas stream, just behind the point of divergence. For the case of WC/Copowder, this system allows a spray rate of up to 10 kg/h without affecting coating quality.

During combustion of liquid fuel and oxygen chamber pressures of 10 bar and more are generated. This results in jet velocities of more than 2000 m/s. The generated heat isroughly doubled compared to gas operated systems. Temperatures of maximum 2.800° are achieved. C Using the GTV HVOF K2 burner thermal spray coatings with low porosity (< 1%) high bond strength (> 100 MPa), low oxidation and high resulting hardness can be achieved. Another advantage is that coatings with highly compressive residual stress can be sprayed reaching several millimeters thickness. The powerof the kerosene oxygen mixture is more than 250 kW (about 10 kW per liter kerosene). Thus feed rates of 10 kg/h can be realized.
1.3 WATER QUALITY
Use water with a low hardness (about degree 2 hardness). Lime accumulation could damage the torch.
