HVOF Coating Materials
In the realm of alloy coating facilitated by advanced guns, numerous kinds of plating or dusting powders can be employed. These include chromium carbide, aluminum oxide (alumina), cobalt-chromium, nickel-chromium, zirconium oxide (zirconia), boron carbide, titanium dioxide, and various polymer powders.
In the context of HVOF guns utilized for tungsten carbide coating, the coating thickness typically ranges from 150 µm (microns) to 300 µm (microns), equivalent to 6 mils to 12 mils. The actual thickness is determined based on specific requirements, such as hardness, design, mechanical needs, and thermal conductivity of the metals being plated.
HVOF Coating Thickness
According to standards, HVOF Tungsten Carbide Coating exhibits a thickness ranging 1 mils to 20 mils, however translates to approximately 25 microns to 500 microns. This thickness may vary depending on the material's specific demand of the application where plating is used with the HVOFspraying gun.
HVOF Coating Temperature
During the process of coating a metal surface using an HVOF gun, the temperature typically ranges from 2800°C to 3500°C, equivalent to approximately 5000°F to 6332°F when converted from Celsius to Fahrenheit.
Several factors come into play in influencing the temperature of High Velocity Oxy Fuel coating, including:
Oxygen flow rate
Fuel gas used to like – LPG
Air Pressure
Coating powder selection
By adjusting these factors, the plating operation should be optimized to achieve the desired results for different applications.
HVOF Coating Process Explained Step-by-Step
Given below is step-by-step tungsten carbide coating operation with the help of HVOF spray gun:-
Step -1: Surface Preparation for Coating with High-Velocity Oxygen Fuel (HVOF) gun
To initiate HVOF operation procedure, the first step involves preparing surface. This includes removal of rust from the metal surface through grit blasting or shot blasting techniques.
Step -2: Material Selection for Coating
In this step, appropriate coating stuff is established on the specific requirements of the surface. Material selection may pivot on the type of metals, alloys, carbides, or other materials to be coated.
Step -3: Powder Feeding with LPG, Air Compressor, Oxygen & Nitrogen Gas Connection
Next, the chosen coating powder, such as Tungsten Carbide or Chromium Carbide, is filled into the powder feeding container. The powder is then fed into the combustion chamber for the coating process.
The HVOF spray gun for Tungsten Carbide Coating is connected to various components, including the LPG, air compressor, oxygen, and nitrogen gas supply, through pipes and control panels.
In Other Words :
In the third step choose the powder that you fill in the powder feeding container, for Example - we select Tungsten Carbide or Chromium Carbide and fill in the combustion chamber for coating.
After filling the powder in the chamber box, connect the LPG pipe to the cylinder on one side and to the HVOF coating chamber on the other side. After that connect the air compressor pipe from one side to the cylinder and the other side to the HVOF chamber.
Then after it is connected, connect the Oxygen gas pipe from one side to the cylinder and from the other side to the HVOF chamber. Finally, connect the Nitrogen gas pipe on one side to the cylinder and the other side to the HVOF chamber.
