6)High performance F4 plasma nozzle(anode) and F4 electrode(cathode)
In the plasma spraying process, metal or ceramic powder is melted in a plasma arc and then sprayed at high speed onto the workpiece to be coated. In this way, water-impermeable, highly adhesive coatings can be deposited on tools and various equipment components. When used in spray guns, our electrodes must be able to withstand transient plasma temperatures in excess of 12,000°C. This kind of instantaneous high temperature and pressure is not a problem for our F4 electrode. Our company uses back-casting production technology to form a seamless connection between tungsten and copper, which is extremely strong. Therefore, our electrodes can provide stable working conditions for a long time and extend their service life.
Different from the brazing method, brazing uses solder as an intermediate medium to fuse the two alloys, but it is difficult to achieve 100% connection. Therefore, the product produced in this way is first of all not strong enough and is not suitable for the extreme conditions faced in the gun body. High pressure and high temperature can easily cause uneven heat conduction and cracks.

Advantages of plasma spray nozzles and electrodes produced by our company:
1. Our company has been engaged in the production of pure tungsten and tungsten alloy materials for many years, and has an in-depth understanding of the structure and properties of materials. For the tungsten electrode used in plasma spraying electrodes, based on our full understanding of the application, we have made more improvements and treatments to the material structure to meet the material requirements of plasma spraying. By densifying the tungsten electrode, a finer, more uniform grain structure is formed. The modified tungsten alloy has relatively high hardness and density, fast arc starting, excellent resistance to arc burning loss, and long life.
2. Our company's plasma spraying electrodes and nozzles use unique back-casting technology to achieve seamless bonding between tungsten and copper. The bonding strength can be as high as 127MPa, while the traditional bonding strength is less than 100MPa. Compared with traditional brazing, joints made by back-casting have higher bonding strength between tungsten and copper, larger contact area, more uniform resistance, and stronger heat dissipation ability, making the nozzle and electrode more stable and more durable as well as long service life.
3. We produce tungsten electrodes of different materials (good arc starting performance and ablation resistance). Based on customer usage conditions, we can provide more suitable materials for customers to choose.
| Material | Impurity content (%) | Electron work function (eV) |
| Lanthanum tungsten | <0.2 | 2.8-3.2 |
| Cerium tungsten | <0.2 | 2.7-2.8 |
| Thorium tungsten | <0.2 | 2.0-3.9 |
4. Based on the research and analysis of plasma spray guns, the electrodes and nozzles produced by our company can perfectly adapt to the original spray guns, and no additional adjustment of spraying parameters is required during replacement. We have a complete product series, and the plasma spray electrodes and nozzles we produce can be widely used in F4, 9M, SG-100 and other spray guns of Metco, GTV, FST, AMT AG, Praxair and other companies.
5. We have rich experience in producing various cathodes and anodes, which can be customized and processed according to customer samples or drawings. We can also provide semi-finished products with seamless combination of tungsten and copper.
We can ensure our all products which are seamless bonding,no gas foam generating,and assure concentricity,if any defect has been found which are due to our cause,we can replace them for free and send you along with shipment for next time.
