F1 Cathode, F4 Plasma Copper-Tungsten Spray Electrode

Product Description

We supply various kinds of plasma spray electrode with tungsten insert including F1 electrode,F4 electrode and so on.

Premium F1 nozzle and electrode
    With the advent of FST's F1 plasma gun, which has for some time been known for its reliability, good coating quality and is suitable for coating internal surfaces up to 75 mm (3 inches) in diameter or larger.
    The F1 is equipped with a tungsten nozzle, similar to that used on the F4 gun, for long life, minimizing parts replacement and production costs.
    The F1 is designed to operate efficiently with continuous power up to 25 kW.
    F1 has two spray angles to choose from, F1-90 and F1-45. Our company's F1 nozzles and electrodes can match either one without changing parameters.
    F1 electrodes can be divided into two categories: one is threaded copper-tungsten electrode, and the other is unthreaded copper-tungsten electrode.
Due to the use of high-quality raw materials and the back-casting method combining copper and tungsten, as well as advanced technology and the introduction of advanced foreign equipment, the F1 plasma nozzles and electrodes provided by our company are high-quality, affordable and cost-effective products.
The foreign market is very popular.

Our Advantages

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.

After Sales Service

 

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.
