F6 Plasma Spray Gun Parts Copper Tungsten Electrodes and Nozzles

Product Description

 

Plasma thermal spray gun consumables
    As we all know, the most critical components of plasma thermal spray guns such as F4, F1, 9MB, 7MB, 3M7, SG-100,SinplexPro,TriplexPro and so on are the nozzle and electrode . These two products are also consumable parts and are one of the most important consumables in plasma thermal spraying.
    Our company is a manufacturer specializing in the production of plasma spray electrodes and nozzles (also known as plasma cathodes and anodes, tungsten copper cathodes, and tungsten copper anodes).

 

 

Focus on the GTV F6 Plasma Spray Gun: A New Milestone After the F4

In the field of industrial surface engineering, plasma spraying technology has become a core surface enhancement method in industries such as aerospace, energy, and high-end manufacturing, thanks to its excellent coating performance and process flexibility. The F6 plasma spray gun launched by Germany's GTV company, as an upgraded iteration of the classic F4 series, redefines the preparation standards of industrial-grade coatings through systematic technological innovations and a modular design concept.

Engineering Breakthrough in Single Arc Wide Adaptability of the F6 Gun

The core innovation of the GTV F6 spray gun lies in its single-arc dynamic control technology, which achieves precise control of the plasma flame energy through electromagnetic field optimization and gas dynamics design synergy. Its core technical advantages include:

• Full-spectrum nozzle compatibility: A single arc can freely adapt to cylindrical nozzles with diameters of 4-8 mm and de-Laval supersonic nozzles, enabling coating process switching without adjusting power parameters.
• Improved arc stability: The optimized magnetic field distribution results in smaller arc fluctuation ranges compared to the F4, providing a more uniform thermal energy environment for powder particles.
• High-speed deposition capability: When used with the de-Laval nozzle, particle velocity is improved over the F4, significantly increasing coating density and bonding strength.

Technical Advantages of F6 Plasma Nozzle
 

• Exceptional High-Power Stability
  Engineered to withstand prolonged high-amperage operations, ensuring a highly stable plasma arc even under extreme thermal conditions.
• Superior Thermal Conductivity
  Manufactured from premium-grade copper alloys with optimized internal cooling channels, significantly accelerating heat dissipation to extend service life.
• High Coating Quality and Density
  Delivers a highly concentrated plasma jet, which provides optimal melting of powder particles to achieve low-porosity, high-bond-strength coatings.
• Excellent Wear and Erosion Resistance
  The advanced geometry and robust material composition minimize inner bore erosion, maintaining consistent spray patterns over extended use.
• Optimized Powder Utilization
  The precision-machined nozzle profile ensures a uniform thermal transfer to the powder, leading to higher deposition efficiency and reduced material waste.
• Seamless Compatibility
  Perfectly matched with standard F6-type plasma spray guns, allowing for quick replacements with minimal downtime.

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
