Thick and Thin Tungsten Plasma Spray 9MB Nozzle 723

Product Description

We supply 9MB Plasma Spray Nozzle with tungsten insert for 723 GH nozzle.

We are professional producer for all kinds of plasma spray electrodes and nozzles.

Product quality is comparable to OEM parts but with much lower prices.

Whether you buy plasma spray parts from Metco, GTV or other companies, you can contact us for the suitable parts.

For 9mb Nozzle, we can supply pure copper nozzles and tungsten lined copper nozzles.

And we know each model, if you need one of them, just tell us your model number.

We can provide to you without your drawings.


Plasma spraying is a technique for surface strengthening and modification.

A DC arc-driven plasma arc is used as a source to heat the metal or ceramic powder to a molten or semi-molten state, and to spray the workpiece at a high speed.

In the spray gun,  the electrode are subjected to extremely high temperatures. The high melting point of tungsten and the high thermal conductivity of the copper material make the nozzle and the electrode to obtain excellent arc corrosion resistance, high temperature resistance and optimum thermal conductivity.

Our company uses back-casting method to realize nondestructive combination of tungsten and copper, and obtain stable and reliable connection of tungsten and copper.

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.
