9MB Copper Tungsten Plasma Cathode for Thermal Spray Gun Consumables

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).

 

Supply of plasma thermal spraying 9MB nozzles and electrodes

The 9MB plasma spray gun is a versatile tool in the thermal spray industry, known for its high power and compatibility with a variety of process gases including argon, helium, hydrogen and nitrogen. It comes in machine-mounted and handheld variants, with the machine-mounted version weighing 3.6kg and the handheld version weighing 3kg. The 9MB series are well-known plasma spray guns, especially the Metco 9MB model, supplied by the company Oerlikon Metco.
The 9mb nozzle has two structures, one is pure copper without tungsten inlay; the other is a copper inlaid tungsten nozzle.
For nozzles containing tungsten, we can back cast the nozzle. Backcasting is more expensive, but also lasts longer.

Advantages of copper inlaid tungsten nozzle.
Copper blowout can be eliminated by inlaying tungsten into the copper nozzle.
 Tungsten performs better in a plasma arc due to its higher wear resistance compared to copper, so they can help control process excursions for longer service life.
Tungsten-containing nozzles last longer and reduce gun maintenance compared to standard 9MB nozzles.
It can reduce waste materials and reduce the number of nozzle replacements.

The conventional consumable accessories of the 9MB plasma spray gun include electrodes and nozzles. Our company provides matching electrodes and different types of nozzles, such as copper nozzles and copper-inlaid tungsten nozzles.
In addition, the two nozzles of 9MB are common with the nozzles of 7MB, 3M7 and 2MB.

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.
